Gavin, Thanks very much for this thorough explanation. I appreciate your time.
However, I don't think it will work because they're also blocking all outside ports. Port 80 and the port used for ftp are opened, but I doubt they let any outgoing traffic on any other port. We really feel like in a prison here... Any other idea which would work on port 80? Although, now that I think about it, port 80 is closed by Verizon, so I wouldn't be able to access my PowerMac running OS X at home. I can't access my web site from work because my web server at home uses port 8080.
