Personally I think you're on a hiding to nothing if
you try to do that, what we do is provide multiple
compilers and recommend to our users that they test
their code themselves.

Not a direct answer I'm afraid, but just wanted to
share our experiences (we've got a 600+ registered
users at present, but they're not all active at once
thankfully).

cheers,
Chris
