The desktop sharing built into Squeak is very nice, but it still needs an IP address to be handed around, which is tricky in a classroom full of kids.
It seems to me that for a classroom situation, a Bonjour- or similar- based sharing system, that let the kids just turn on sharing and see anyone else who was sharing on the same subnet, would be *fantastic*.
Is anything like that available or in the works, or is there some alternative I'm not aware of?
