Not only telemetry, but remote command/control of the
8 bits on  your parallel port!

For telemetry:  Findu.com even has a cgi that will list all stations
in the world that are sending telemetry live.  For example,
my 144.99 alt-input digi in Annapolis sends its battery voltage.
All KPC-3+ TNC's have these 5 channel analog inputs and
output in APRS format.

Also, APRSdos has on-air commands for not only reading
the status of the 8 bits on your parallel port, but also has
an on-air command to set those bits to give you 8 independent
ON/OFF controls for your shack from yoru D7 HT anywhere 
in the world.
