Skype video chat, all the time, works fine. Don't remember about file transfer.
Whenever I am behind NAT and talk to someone else who is behind NAT skype seems to lower the quality, my guess it's because it now bounces traffic via another non-NATed node.
These kind of applications work best if there is at least one non-NATed party involved, especially for video etc.
