Thanks for the detailed answer/thoughts Jon!   Looks like there is room 
for a couple of oddballs like us to play with this mode. :)

I'm so new at this end of the world that I won't comment too much on the 
more general discussion.  The one thing that my being newer to this end 
of the band might add value is this:   Probably being proactive as an 
organization would be a good thing.  There are a large percentage of vhf 
users out there that are only marginally aware of the existence of 
things like ssb, cw, meteor, eme, etc on these frequencies and would not 
really even have them enter their minds.   Consequently I would imagine 
it would be easy for the interests of this group to be overlooked in the 
discussions of band plans, etc.

Hey, thank you all again very much and I look forward to watching this 
discussion.
