As a lowly user, I've not found UP&P to work well for my, on any
network I've worked with it on.
Again, I know my opinion doesn't count for much, but it seems like it
wouldn't be as helpful as other tasks.
I can see two additional benefits, however.
When combined with a delay in Keepalive/Handshaking for properly
port-forwarded nodes, this could allow more bandwidth to be used for
actual traffic, rather than infrastructure.
This would increase the number of users who are accessible to those
who do not know their IP address. (These users can only access
someone who is properly port forwarded)
