A way I thought might be feasible is having the actual games run on servers and then dump the game logs in a simple format, so they can be played back with either the original game or any kind of player people come up with, eg browser-based. Concerning the integer vs bit, that was what I meant, was still thinking in terms of C ints. An even more extreme version would be to force the agents to store their state in a similar manner, but I think that would be taking it too far.
