This is something that I think would be nice for the Flash client. It would most certainly give BYOND games more notoriety, and BYOND itself. After you publish the game(via hub) you're provided with a link that can be embedded into web pages(like YouTube), you can then play the game like you would play a YouTube video, except you're playing as a Guest or something if you don't have a key? I don't know. PlayMyCode does this and it's pretty awesome.
