Yeap, that is what the protocol is supposed to do.  Napster (sender)
pings the napster (reciever) to find out what type of link there is
between them.  There is supposed to be bandwidth limiting features
coming out soon, so this feature was added a while back so the
information would be there.

Note: I don't work for or use napster, I just read the reverse
engineered protocol documentation from time to time.
