[aprssig] APRS DF reporting

To all... I'm a new member and have no prior experience with APRS or any
packet modes, but I am considering something that might interest folks here.
I'm Bob Simmons, ( WB6EYV ) and I make the PicoDopp DF, which is a DSP
Doppler DF with RS232 output and a GPS input.

 I recently had cause to investigate packet and APRS technology for a
potential customer, and I now think I could add automatic APRS DF reporting
to the PicoDopp, without too much trouble. ( or offer it as a separate
optional board ) It would have a PTT output, an audio input to check for
channel = busy, and a tone output. I would also have to create an IBM
program to set the semi-static variables ( like the user's call sign,
destination address, etc. ) which would be stored in EE memory of the PIC
chip, and which would not change during normal operation. It wouldn't be
terribly easy to do all this, but I think also not terribly hard.

 I want to solicit opinions and comments on this, and suggestions for
features. I don't want to turn this into a major engineering effort, but if
there is an interest out there for such a beast, I probably will pursue it.
Offers to critique and test the design ( if I proceed ) would also be
