One of the first GSoC students worked on file transfer with official ICQ
clients and UPnP issues (at least on the oscar side), where he actually
had to implement some of the protocol side. I didn't know how complete
your direct connection work is, and I had the impression that it's
mostly working, which is why I didn't think that's enough work to
warrant SoC.

However, I think working on improving our proxy code and auto detection
around firewall would be a great SoC subject, with or without involving
file transfer.
