I may be missing something but how could you not build this into a large scale, Tier 1 MMO?
It wouldn't probably alleviate most if not all of the server congestion problems.
I know people who have said they basically logged on and just went AFK for hours on end so they knew they would be able to play whenever it was convenient.
Is it some sort of cultural thing in Asia to force boot AFKers that is frowned upon?
