How to get nonstandard games going....

[Ghazban]

Yesterday, I happened to be at the V when they got a 5/5 PLO/NLHE game going. This was awesome and a game I'd play every time I went to the casino if it were running. Short of calling up a critical mass of players to schedule a time and date for such a game, is there any good way to get games like this (i.e. not straight NLHE or LHE) started? Just start an interest list and hope?
