[AG-TECH] ANL bridge machine and port info?

How would I go about running the server on its own? The binary that
comes with the AGConnector package complains about being run incorrectly
but doesn't give any useful information. I'm having trouble finding a
UMTP server that I can run on a central machine. I'm modifying the
AGConnector python script to have this machine as the default, so people
should be able to run it without configuring a new server.
