That's going to make using the UIview local server the way I described 
impossible since the main connection (public-facing side) of UIview is 
already using port 14580 for login to an Internet server.    I hope 
Chris will consider making this port changeable, perhaps through a .ini 
or other config file.

The UIview local server is a very useful tool.  It allows multiple 
machines on a LAN (or multiple applications on a single machine) to 
share data from the Internet connection of the first copy of UIview.   
It also allows the client machines to see everything received by the 
host machine's TNC(s) if any.  Further, the local server is 
bi-directional, allowing the client machines to send data to the 
host/master which in turn can plot it on it's map and/or send it to the 
Internet.   It reduces the loading of the Internet servers and conserves 
Internet bandwidth by allowing all the machines/APRS apps on your LAN to 
use only one Internet login.  (Instead of the usual kludge of multiple 
SSIDs with separate logins.)

The local server really shines in EOC-type scenarios where it can allow 
multiple workstations on the LAN to all see exactly the same traffic.  I 
have even port-forwarded the local server connection through routers to 
the Internet and then back through a second router miles away so that an 
APRS app on a PC in a basement office, with no radio, could use the data 
being heard by a copy of UIview with a radio/TNC located on the top 
floor of another building on a college campus.
