How to work implants into the game

[phungus]

I've always figured implants were a bad idea. But someone here posted about them in the GU13 proposed list changes thread I thought made sense. Implants cost Certs/SC to unlock, once unlocked they could be purchased for the time limit by resources.

That made sense to me.

What were some other ideas. How do you guys think they will make implants work (it's a good way to get revenue, I can't imagine they'd abandon them).
