About
We are establishing a network of XO laptops to run experiments on campus and we would like to have as many laptops in East Campus and Senior House as possible. Other people from around the campus will eventually participate also, so this may be a good chance to chat with other users directly and possibly make new friends!
Participation terms
Would you like to participate? You will be able to use the laptop as much as you want, in (almost) any way you want, as long as you feed it (with power that is) and don't break its connection to the rest of the network. This means that the laptop must be constantly connected over ethernet cable for remote access (mainly for software updates), while the wireless network is used for communication with other laptops.
Termination
The laptop will be the property of OLPC and you may be asked to return at any time.
Network layout
The network in the end will look something like this: Network layout
More laptops may be added, depending on availability and position in campus.

This is a zoom in on buildings 62 and 64 (the two parallel buildings of East Campus), building E2 (Senior House) and E15 (Media Lab). There is a slight chance to achieve connectivity with building NE18 (OLPC at 1CC) and building E55 (Eastgate).
