Remember, in peer-to-peer the guy behind the firewall initiates the 
connection.  (And on mc it should be TCP.)


Even this might be blocked on some firewalls.  A couple ways to 
address this comes to mind.

First, you can used a standard chat protocol.  That makes it easier 
for the person behind the firewall to explain what is needed to the 
firewall guy.  Alternately, you describe exactly what is needed 
that can be printed and handed to the firewall person.

Second, you can look like an allowed protocol.  Many applications 
use HTTP.  If there is also a proxy, the dialog must look a lot 
like HTTP.

These don't seem to be the problem in your particular test case.
