Heh, true, but the general problem applies to more than file sharing. In my
case, I'm writing an application that would be used inside exactly this type
of network, and the adoption-pattern generally starts with a couple guys
wanting to test it out before they can convince IT to punch holes in the
firewall. Right now I support a relay-service as a fallback, but I'd love
to offer NAT-to-NAT and Firewall-to-Firewall where applicable. Thus the big
question is my mind is: if I implement this feature, how many users would
actually be able to take advantage of it?
