Decentralized Dice Or Decentralized Poker - Is This Possible?

[WhatTheGox]

As much as i like primedice with openbazaar recently launching it got me thinking of what innovations were possible in the gambling world.

Decentralized dice decentralized poker with no house edge or rake would be pretty amazing creations.  With dice i guess the network would just be one massive PVP system and super fast rolling wouldnt be possible without a house bankroll.

With poker, a centralized non rake site has always been unsuccessful previously due to no money for advertising to attract players. (Side note: Im concerned openbazaar might not be a big deal for similar reason.)

So yeah... any of the above currently possible?
