Our problem is that we know of no other users! If we did it might help a great deal.
My problem is that I don't know if my packets are getting out or if they are whether they are not getting to his computer for whatever reason.
You may find that playing around with a packet sniffer (tcpdump) and seeing which way packets on the network go to which machine etc. may provide you with some clues. I would suspect that the problem is a firewall on one of the machines, although not knowing how this software works it is hard for me to say which one :) Are there any logs for the firewalls that you could look at?
If tcpdump looks like it is a bit heavy to interpret you may find that using ethereal as a front end may help you http://www.ethereal.com/ trouble is that I can't really give you a quick and dirty guide as to how they work, you will have to give them a go yourself.
