You know my feelings already.  These suggestions will enable real HF 
modems for the first time.  I would not  have dreamed of building a 
reasonable HF modem until the League proposals were brought forward.  It 
would have just been a waste of time.  I would have been run out of 
amateur radio for even suggesting doing MS188-110A,B, etc.  on (say) 20 
meters in the phone band.  Now I can see
doing some serious work and it actually could be interesting at last.  
We could have 19-50 Kbps NVIS modems kicking some real butt in 9 Khz 
bandwidth.  Since OFDM - fade designed trellis QAM seems like AM to me 
anyway.  ;-).   Imagine having really serious digital voice over NVIS 
channels with S9 signals on 40 meters and running 5 watts.  Bring it on!
