Perhaps, rather than trying to explain bits of your theory into my own view, (Stupid idea, really, but interesting debate) I should explain how I consider it to work.
A friend of mine, back in DnD, came up with a view of how Arcane Magic worked. It makes a whole lot of sense.
'The Weave'. If the infinite reaches of the multiverse are a single tapestry, then Arcane Magic is the thread that holds it together.
I go a bit further with that. If you're twisting this thread this way and that, it's going to get bent out of its place. (Mana Storms, UGE, anyone?) It can be, eventually, shifted back into order, but that takes interference, time, and effort beyond what it took to open things up in the first place. While that thread is out of place, there's a 'hole'. If, say, that tapestry was packed in a heap with a few thousand others in a warehouse, and an adjacent tapestry had some thread out of place...
Hey, look. Shedim.
Resonance, then, would be technology so advanced as to be able to perfectly (Or nearly) mimic the way the universe itself works. Perhaps because Mana is affecting the unseen ebb and flow of data, but, in a way, humans have created a 'tapestry' within their own. Technomancers are in tune with this. Perhaps they can be considered 'moderators' or 'administrators' fixing bugs in the system.
If Magicians and Adepts are unconsciously 'aware' of the 'hole', of the loose thread, and able to take advantage of it, they are essentially granted the ability to eventually fix the hole. They are the Tapestry's self-repair system.
Resonance is a newer force. It's brand new, and buggy. It doesn't need to be 'repaired', it needs to be 'upgraded' and 'improved'. Functionally, many things that Technos and Mages can do are similar, in their respective worlds, but for different purposes.
Much like your theory, RHat, quite unpolished. Some parallels exist, here and there. Your take?
