Sounds good to me.
I, originally, had thought this is what it meant by groups. Of course, I was wrong, but still. Networking would be awesome, but it is kind of a big change. I personally don't think this would be easy to program either. Either that, or there's some exploits people could use.
That, and as an add-on to the idea, maybe(if this is even implemented) you could pay for multiple networks as well, instead of having all your servers interlinked at once. It seems like a smarter idea to me, having a back-up I mean.
