I've started looking at _all_ files in svn and checking their respective license to see if it's GPL'd or at least has another Free Software license. Also, all such licenses must be GPL compatible, too, AFAIK (but I'm no lawyer).

Wow thats quite a list. Thank you for doing this. This is also going to be very important for OLPC. We will be releasing some stuff in the near future and I'm sure this issue will come up.
