word of warning: long post being a summary of all my experiences and results so far, I apologize, but really didn't have the heart to cut it down, you're more than welcome to skip 
I'll tell you this much - I know that some people way back when Peter just started with these projects were reporting really extraordinary things, I even remember someone wrote about setting power on original Aquaware to 100% and going through a kind of a portal/black hole/whatever.
That's really an outlier result so to speak, but most people just get something positive - a feeling, buzz, warmth, something along those lines.
Some can feel energy coming off from the programs, at times almost too great to handle.
To some people it seems it turned their world 180* to the better, for some others it did, as far as I know, nothing.
What about me?
When something peeks my interest I like to know as much as I can about it, so I've experimented quite a bit with all of the available software here.
I love to take a scientific approach to things (it's really a prerequisite in my field of duty so to speak) but still I don't try to overdo on the suspicion/disbelief part, I try to prove things if they are as they are said to be.
Most people would dismiss this right of the bat, but thinking something is impossible just limits you.
So, I have charged water, food, air, various items/things, soil, plants, myself (both whole and "partially" like focusing on a wound). Something I've done only several times, others like water probably approaching 500 uses or more perhaps. Where applicable I've tried a lot of duration and power settings, yes even the 100% "black-hole-please-don't-suck-me-in" intensity quite a few times and I'm still here with my head in one piece nontheless

My results/impressions?
1. Water, and perhaps even some other molecules, definately change in whatever you put your focus on.
If you charge simple plain water it IS different. No doubt about it. I've done a blind and double blind experiments with my family/friends who have/had no idea about these programs and they (as well as me ofcourse!) notice the difference easily in favor of the charged drink. Beverages produce even more impressive results. The water is softer, it's tension is lower, it just feels smoother somehow. Taste is changed.
2. First time I'm introduced to any of these programs and the first time I charge water with these I feel light-headed a bit, sometimes feeling "waves" from the program. After first couple of usages this effect is gone and rarely appears again.
3. Charging something other than drinks produces really interesting results, some of those are unverifiable cause of the subjective nature. Objective ones for me include better plant growth and appearance. Subjective - charging items makes the "feel" different when being around/touching/using them. Food has something specific about it that makes you not want to eat non-charged food anymore unless you haven't got a choice. Using it on myself sometimes did nothing, other times I could feel the "waves". Using it on wounds and/or medicine used to treat those results in immediate pain relief, increased and more effective healing. However, all those things except plants (and even maybe those!) can't really be proven.
4. Ingesting charged water produces relatively quickly, after only a minute or two, a slight feeling of warmth, something making you warmer from the inside. Same kind of a warmth you get when you feel really good for doing a good deed. It lasts for several hours as being noticable, but I suspect it is "active" almost a day although you can't feel it anymore. Changes in behaviour are slight, but are there, more positive attitude and perspective on things in life, feeling of slightly increased energy to deal with things, both psychically and physically, I find that I can't be "bothered" to be negative.
It's kinda like you put on glasses with lenses that color everything a bit more positive, but so subtle. Personally I find altering of my state hardest to describe. It's in the little things, the details, but it's there.
And I've charged our homes water supply quite a few times through periods with only me knowing that and observed the behaviour of my family, let's just say it's interesting

Later I've filled them in, they really don't mind, they think it's crazy to even consider this works but I've seen otherwise

Basically every program had the same effect for me, but they differ in percieved "strength" of the effect. For me it's from the strongest to least strong: Navitus>Aquaware>=12th Project libraries>Neocode>=Aliix.
It's weird, but the Aliix and Neocode did very little for me compared to others and something felt just "wrong" with the glyphs, especially moving them. But Navitus is really something else and I can't wait for what Peter's got in store for us.
So that's the gist of all my experiences, hope you didn't fall asleep too many times reading this
