And it's not even that simple. Lets say that machines A and B (of owners A and B) want to collaborate, and they are using salut / multicast. Both machines are asleep. Laptop A is woken up as the user starts an activity and shares it. In person, the owner A tells owner B that the activity is now shared. Laptop A goes to sleep. Laptop B is woken up as the user presses the neighborhood view button. Laptop B broadcasts its state and asks for a resync of other nodes (under the above questionable idea). Laptop A does not respond because it is asleep. Owner B goes over to owner A and says "hey, I don't see it". Owner A says "OK, I'll try again", and stops and starts a new activity and shares it on laptop A. Laptop B goes to sleep during the above. Laptop A goes to sleep soon after sharing the activity. Owner of B goes back to laptop B, which is asleep while showing the neighborhood view. "Hey, I still can't see it" etc. _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
