If someone reverse engineers the skype protocol it would be possible to
use these media relays as a real big anonymizing proxy network for a
filesharing tool by
simulating skype calls over it.
Depending on the way those relays are implemented it could also be possible to
proxy arbitrary data (e.g. smtp proxies).
If that happens it could be a real problem for many skype users.
