Okay, to play devil's advocate:  just WHAT would you have the software 
listen for, to determine that a frequency is in use?  I'm no software 
engineer either, but it doesn't take one to figure out that you're looking 
at crippling the functionality of the program with too simple an algorithm, 
and making it terribly bloated (& expensive), and possibly still crippling 
its functionality, if you cover ALL the possible bases.

The only reasonable solution that I can see is to relegate semi-automatic 
operation to a small set of discrete frequencies, like the beacon system, 
and we all steer clear of them.  There needs to be at least this one 
exception to regulation-by-bandwidth.  That will go in my comments to the 
FCC.

Nor should any software developer be required to give away the fruits of 
their labor for free:  that would have a very chilling effect on software 
development.  The FCC will  never agree to that, nor should they - that's 
entirely outside their authority.  (Unless, of course, the Commission is 
going to write the decoding software & give it away...  yeah, right!)

Listen-before-you-transmit will never be perfect:  there will ALWAYS be 
cases where a 3rd party cannot hear the others on frequency.  It happens 
under LOCAL control, every day in every mode, even on FM repeaters, thanks 
to odd splits and PL!  (You should hear it on SSTV and the satellites!)  The 
only way around it with semi-automatic operation is as I pointed out above: 
semi-automatic stations should be restricted to operation on discrete 
frequencies so that users of other modes can avoid them.  So let's all 
propose that in our comments.

Sorry, that one's not gonna fly:   97.113(a)(4) prohibits transmissions 
"...in codes or ciphers INTENDED TO OBSCURE the meaning thereof..." 
(emphasis mine).  That's quite different than how you are attempting to 
apply it.  Lack of software to decode a transmission on your end doesn't 
equal intent to obscure on the sender's part........  In reality, the only 
people who could legitimately claim to NEED the decoding software would be a 
repeater operator whose machine is being used to relay digital 
transmissions, and the FCC itself.
