That would only work for your own station, not for any others you
wanted to plot.

Perhaps a UDP listening socket via a new interface.  That way you
could enable that if you needed the functionality, and Xastir could
receive packets through that mechanism.  Whether it would have
enough "smarts" to talk back out through that port to various
clients is another matter though:  Might require quite a bit of code
to keep track of clients.

Except for changing the symbology, which appears to be a main goal.

Yea, it's all 2D.  It can keep track of altitude, but it can't
display it in 3D.
