I can understand from a commercial perspective why having a permissive 
licensed production compiler could be good.. I can understand why many 
people don't like gcc or fsf, but what does the BSD community get?

1) Performance?
2) Robustness?
3) ... ?

What's really the goal here?  What problem are you working to solve?  
May I humbly say that building software with a different compiler in 
itself doesn't really accomplish anything.

Starting early can give valuable feedback , but without actually having 
the resources to follow-up it's wasted effort.  Is llvm at the point 
where it can self host BSD?  If not why not start there?  Maybe identify 
the most used applications..

I don't waste time on front-end work though so this is of course my 
humble opinion..
