Not in the way it is currently set up --- we have 7 or 8 test systems 
and each one generates an email with results. It may not be too bad if 
all tests pass but if they fail each email may have as much as 2-3 MB of 
logs (we don't upload them anywhere).

I could generate a summary of a nightly run but then we have some 
intermittent failures mostly on some older distros (like Fedora 15) that 
we are unlikely to ever look into so that may make things confusing 
(Yes, the question is then -- why do we even bother running it).

Yes, perhaps have a devel/oss branch that tracks the latest 
devel/for-linus-<version>? David?
