There's a few ideas I've wanted to put out there so here goes:
The 72 game. UB and Absolute Poker used to have '72' tables where everyone tabled 2bbs every hand and if you won a hand with 7-2 you won the bounty. Lead to an insane and entertaining dynamic, and in this day and age would also thwart bots somewhat.
On the subject of bots, I think in future online poker might need something like a rotation of slight rule tweaks, so jokers wild, or an extra suit, that kinda thing.
That is all.
