I believe i know the answer but I want to be sure. Say you have Chaos Theory as your id. You have no programs installed but have an omni-drive. If you install overmind, can you, on install, host it on omni-drive; thereby giving you 5 power counters on it instead of 4?

I assume you can because i read that you can install a program on an empty dinosarous with no mu left without trashing anything

I see no reason this wouldn't work.

Yes.
