Your optimal Matrix rules, How should the Matrix rules be in your oppinion? Options

[Kyrel]

Inspired by the thread on the 5th ed. Matrix I have a question for you all.

How should the SR Matrix rules look in your oppinion? What would be the core mechanic? The underlying goal? What should the processes involved in hacking be?

I've been considdering the matrix rules for a while, and to be honest I still haven't made up my mind on how I would like to make them, if I was designing them from scratch. However, given the amount of experience here on Dumpshock, collectively we really ought to be able to come up with some decent, functional rules for hacking.

So, anyone up for a discussion on how the matrix rules could be made, and why they should be made that way? No holds barred. Forget history and how things have been done up until now, and let me know your thoughts on the matter.

I'll pitch in at a later point. It's crap O'clock where I'm at right now, and I'm heading for dreamland.
