[NLRS] Left Field (or maybe even outside the ball park) thought on VHF Field Day modes

For more "local" contacts, what about using "Audio Over FM" 
("AOFM"?) for digital modes? Perhaps even CW?

When I was watching an FLDIGI demo sometime back, I had my 
laptop "on", running FLDIGI and IN the receive mode, the 
transmission that was being 'copied' in the demo started 
appearing on MY laptop, just as it was on the computer screen 
that was showing in the demo, with just audio coupling to the 
actual microphone (NOT the mic input) on my laptop.

For transmit, just hold the mic up to the laptop speakers.

I think that would be in the *spirit* of the rules and 
legitimate to call it a 'digital mode' contact (or a CW contact 
if CW sending were used and regardless of how the CW were copied 
as long as it actually WAS copied accurately by a person or by a 
computer program), even if not specifically allowed (or 
prohibited).

Or would that be considered too 'outside' of the envelope?

Just an idea, that I've not really TRIED (as it was 
'happenstance' on the receive part and I definitely have NOT 
tried the transmit part) and I really don't for sure that it 
would work but it seems possible.

I'm a little bit far away from the Twin Cities to try it with 
anyone there but offer the idea for anyone (anytwo?) who might 
want to experiment. I'd just appreciate that if anyone does (or 
anytwo _do_), that you share the results of your attempts at 
this with me as a minimum or I suspect it might be of interest 
to the reflector.
