Yes, straightforward.  You don't even need audio out, just PTT and
GND (to the keyer input).

The more difficult part is needing stable rigs on both ends in order
to have automated software copy you (unless you're using something
like CW Skimmer I suppose).  CW signals are quite narrow.

You'd also need software to convert the received CW back into an
APRS type of posit, perhaps injecting it into the APRS-IS.

So...  How long in ms would it take to send a CW posit at 30 or
40wpm in Base-91 format?  50wpm?
