The places I would look for an answer to these questions (not in order):
  #1 comp.lang.ads (which you've already done)
  #2 The GNATLIST mailing list (gnatlist@hermes.gwu.edu)
  #3 The gcc mailing list (http://gcc.gnu.org/lists.html)
  #4 Contact AdaCore (http://www.adacore.com/home/)

If you are serious and have the funds to support using Ada, contacting 
AdaCore is your best bet.  The last I knew you could get trial support from 
AdaCore and evaluate their full product.

I hope this helps,
Steve
