Around here, we're in transition.

The coordination body made room for digital/narrowband technology in the 
UHF and higher bands, but VHF is stuffed full.  One group has a VHF 
allocation in the works, and we have no current VHF backlog, but there's 
more coming.  VHF will be the place where some difficult decisions have 
to be made if digital/narrowband folks really need VHF.

Most digital technolgies out there today work fine on UHF, so it may be 
a moot point.  The main "pusher" of VHF will be groups that buy 
repeaters before knowing if they have a frequency to use them on. 
Having a VHF D-STAR module in hand and nowhere to put it, is kinda 
silly.  We know of one group that is going to be in this situation 
because the module was donated to them... with careful location of their 
machine and particular attention taken to coverage area, they might be 
able to be wedged into current VHF allocations... no one's quite sure 
yet how that will work out.  Including them.

Two or three groups have gotten digital coordinations or are in the 
process of doing so in the "segment" of the bands we carved out for 
digital/narrowband.  (I keep using the phrase "digital" because they're 
not all running D-STAR, and this is a D-STAR list.)

I don't see anything stopping the repeater-builders or coordinators  in 
our area from easily transitioning to narrowband technology if hams find 
it interesting/useful... if they do, some analog stuff will have to come 
off-air in the Denver metro area to make it work, but outside of Denver 
things are much more open.

So in my mind the most important piece to keep a transition running 
smoothly is to have a PURPOSE for the D-STAR system.  (Have I thought of 
one yet that's a "killer app" for it?  Not really... but the features 
and technology to have a "killer app" are certainly there.)

The coordination body here refuesed to allocate 12 MHz for that purpose 
on UHF long ago... as you say, blocking 12 MHz of spectrum 100% of the 
time for a less than 1% system, isn't appropriate allocation of 
spectrum.  The ATV'ers here operate on a non-interference basis.  Works 
better that way.

The coordinators also highly recommended that ATV move up to 1.2 GHz, if 
possible.  Much easier to coordinate a repeater coordination there.

Not sure what the ATV stuff has to do with D-STAR, though.  We can drop 
this part of the discussion...

It *appears* to me that most areas aren't really having a problem 
finding space for D-STAR, unless you live in the over-populated coastal 
cities.
