  Ya speaking for Werner and myself we pushed a 2.5 approach. very simply
I think if the community wanted to do anything short term ( say layout 
and design guys they could get a -G put together is short order ( ok 
problems on the wifi interface front) probably best to work from an A8
base. Supply issues perhaps on the Calypso. payback  on investment
is the biggest issue, but It could be brought through EVT with little

  Yup. Now you get why we had such a hard time pulling the trigger on it.
  you have GTA02  shipping  an GTA02 -G that perform better and costs 
less, which kills the 02 and an gta03 in flight which kills them both.
  and then you had conflicts over engineering resource.

  Not really, probably just lowers the risk. Certs run  in parallel and 
havent been critical path as far As I can recall.

Interesting thought. Its probably a tall order to get the community up 
to speed on the whole phone building business building process. I'd 
start with a simple task.. GTA02 -G.. just to give people a taste of 
what one is up against.
