By the way, I did not say the most important thing, this is what the purpose of running your dreamcast interpreter in the browser is that if you can statically run the game on the client (browser in this case, obviously), then I could use the webrts technology to to stream a captured home item to another user at a high frame rate, and use that connection as a channel to forward keystroke data. As you can imagine, this would provide a multiplayer option for mugen players that is still popular and launch any game builds, and all sorts of additional things could be done, but even that would be very cool.
