I've heard that before and I'm not sure I can buy it without seeing some
additional data showing that to be the case.

My intuition tells me that I2 is probably more representative of non-TCP
than one might first imagine.  There are plenty of audio, video,
conferencing and VoIP projects taking place over I2, perhaps in many
cases more so than other parts of the net.  The reason I'm lead to
believe that it would be fairly representative of non-TCP protocols is
because generally the I2 community networks are relatively open.  Its
users are probably much more likely to be able to use non-TCP protocols.
Whereas in many other places, protocols, ports and applications are
often heavily filtered.  In fact, I might be tempted to think that many
of those non-TCP applications you're referring to may often be running
over TCP port 80 to get past filters.
