[Psc] questions for Ext licensing folks

That the way our project is set up should help them sell Ext.js commercial licenses, and that we will encourage people to purchase licenses from Ext.js.  We just want our license to be flexible for both.  So they see us deriving images and names from them as a good thing.

I think I'd be -1 with this. I'd prefer that they don't take business
opportunities into account when answering our questions. Does that
make any sense?
