I've been fooling around with remote access using LogMeIn.com's service (free version). One use I discovered is an alternate way to network your own computers in the same house. Along with remotely using your own computer I can transfer files via email and download them on the client PC. Steps are:
1. Go to your email program(Gmail, Yahoo, Outlook etc..) attach file to email and send to yourself.
2. Using LogMeIn access your second PC(or laptop). Download attachment and do what you want from there. You can print or edit from the second computer from there.
I think it's pretty cool. It's a nice alternative use for the program.
