I think what Ian was getting at was that if Freenet uses SCTP/RUDP, and few 
other 
applications use those protocols, then Freenet traffic will stick out to anyone 
with 
a sniffer.  UDP is fairly common (especially with the popularity of 
multiplayer games), so it's not a big deal.

Of course, this won't be a problem if/when SCTP/RUDP becomes popular.
