you'll have to pick a port on which the firewall doesn't block
traffic. the problem with using the http port (80) is that, due to
the java sandbox, clients have to connect to the same machine from
which they downloaded the applet. it's not possible to have two
applications listen on the same port, so you'd have to figure a way
around that. also, on unix at least, you need root permission to open
ports below 1024, so the vnet server would have to be running as root.
you really need two different ports on the same machine, which
won't be blocked by the firewall. check with your network admin
to find out which ones are free.
