You can link up the two computers with a free remote access program called VNC. Should be available on download.com. It's a host/remote type of program and can be configured to not use a password. Similar to PCanywhere but free although it does not allow for file transfer. As for seeing what's on the neighbors pc, pablo is correct. Unless the users have file and print sharing enabled and you are both logged in to the same network, I don't think you can see what's on their drives and for sure can't see what's on their screen. You would have to install some kind of remote access program on their machines for that to work.
