Eric,
  Replying off list,
 
 Take a look at http://www.digi.com 
They have some RS232 to IP converters.  Kinda neat, in that you can use a
Hardware Serial port on your computer to talk to the remote RS232 port over
the Internet.  You could use UiView on the computer and have it work with a
TNC across town, or on the other side of the world.
 
Some of these units can operate in both directions.  That is, it can
automatically connect to a station, or will accept a connection from a
station.
 
Been looking at these for remotely controlling satellite ground stations,
including D700, rotators etc.  Looks promising.
 
Bill

Has anyone thought about building a modem (TNC) that can be controlled via
IP?  I'm thinking of a modem with a RJ-45 in the back vice the RS-232 and
assign it a static IP and just send data to it.  I could imagine some really
interesting scenarios with that combination.
