Yes, and this does not just apply to Mic-E PTT originated
packets on the end of a voice transmission.  Actually this can
be an application for all of APRS on 144.39.  For packets
without prior spoken voice (as on 144.39), the software will
have to voice-synthesize the call and Symbol before the roger
beep.  In fact, in this case, the speech can be phased into the
virtual position completely:

"WB4APR-VAN-(beep)"
"W3XYZ-HOUSE-(beep)"
"W2GPS-JEEP-(beep)"
Etc...

Decoder would have a range limit and other filters on 144.39 so
that you  could isolate the voice repeorted stuff to only those
of interest to the immediate event or application.

Oh, and of course, it would SPEAK any messages.

Again, this should be trivial.  Just phase delay any audio by
the amount needed for the virtual position.
