No, because a port could be blocked. If you want to send five contents on 
ports 9000, 9002, 9004, 9006 and 9008 but the port 9004 is already in use by 
another application and 9008 is blocked by a firewall, the connection won't 
be established for those ports but will be for the 3 others.

Now, if I understand this XEP is there for testing purpose and will actually 
never be used in real life as ICE-UDP can established a RAW UDP stream if it 
is possible.
