So, MetaPlace. Neat sounding idea - some kind of web-based system/toolkit/API for creating massivly-multiplayer games. The website itself is rather short on technical details, though. This is particularly annoying as this sounds exactly like what I want - a system to create a multiplayer-game for children to play. I want something that emphasises cooperation and puzzle-solving rather than dodging enemies and shooting things - nothing wrong with those sorts of games, but not really appropriate for a school. I was thinking of something web-based, maybe Flash or maybe DHTML, with minimal graphics (easier to draw, easier to program, and easier to view on OLPC screen), mouse controlled (point-and-click on the screen to tell your character to do an action at a particular location). The advantage would be that game logic would be computationally deterministic, you'd only have to send x,y coordinates back to the server ("user a did action b with object c at screen location x,y"), making for very low bandwidth needs.
