Yes, we already have Centos and Caos 2&3 base images that most people  
are using for testing.

These should be coming very soon. :)

It depends on when you are ready to migrate. Our first test system  
was a 512 node Inifiband cluster and it worked without incident. We  
also have several other large prospects on the horizon (including  
vendor partnerships) so production readiness won't be a problem. With  
that said, I would wait until I do the formal press release (waiting  
for the 1.0 tree to finish getting hammered out by our testers and  
initial users).

Thanks for inquiring!
