Although I'm sure Fedora is used productively, it is mainly a "home" or 
"hobbyist" O/S, so I wouldn't count this as a production example.  Had 
you said RHEL4 was using 4.0.3 that would be a different matter.  I 
realise that it might be difficult to get responses at this stage of 
4.x's progress, but nevertheless I thought it worth asking if anyone 
from industry or finance (for example) is using it yet.   When 4.1 comes 
along I'll find some time to run some tests, but before I did that I 
just wanted to hear any stories about peoples experiences so far.

Thanks for that - I'll sign up.

Cheers,
