well hopefully.  I wasn't specific enough in what I was talking about
above.   I said 100 developers.  I should have really said
Large scale development( 100's to thousands of developers, 30+k
files, millions of lines of codes, 500+k revisions, hundreds of
branches ).

CVS just starts to break down at that levels with how it implements
file locking and how it puts all information in the individual ,v
files.

I don't like comparing something that isn't even released( and 
BitKeeper has been almost released for a long time now ) to
existing systems.  In any event BitKeeper sounds good,
but I don't count it towards anything until I can get a copy
in my hand and use it.

I was unaware of BitKeepers multi-site capabilities though,
guess I'm gonna have to go check out it's web pages...
