Epic's own hosting framework (Single - and Multiplayer)

Unlikely, but would be a great idea. There are probably a whole lot of legit technical reasons not to, but are they insurmountable? Disregarding the significant initial outlay that is . . . But as for the “why bother” reasons, well vertical diversification and a little aspiration. If there was a distribution platform implemented, and there was enough incentive to use it (with proper quality control), why not? I mean if you are making games, and a game engine, and you have the ear of so many developers, and the probability is that there will be a few dozen decent games in the next year or two . . . bears thinking about.
