Right; my point being that this server is part of the Yahoo IM system. 
This shows a different mechanism for extending the oob namespace to 
bridge firewalls. The drawbacks are that it might use a lot of disk 
space on the server, that it basically doubles the transfer time, and 
that it's quite specific to file transfer and doesn't allow for other 
types of P2P communication. It is pretty simple, though.
