Hi Adrian and everyone  --

Thank you for the invitation, and I will plan to attend in the morning (I 
have to give a tutorial all afternoon). But, the things you bring up are 
properly in the scope of the chairs and other Space DTF members and not OMG 
staff. I've added the chairs to the addressee list. Adrian, is it possible 
for you to invite them to the Mgmt Council meeting too?
