Hey Michael.  What are you planning to do with the locking stuff?   
I'd like to see zope.locking (http://svn.zope.org/zope.locking/)  
used, rather than zope.app.locking.  It learns from zope.app.locking  
while also addressing some issues and adding some features.  I don't  
have time to do much about proposing it and integrating it, though.   
Maybe I can squeeze in a bit next week or week after.

If Jim successfully gets zc.sharing open sourced today then we have  
some zope.locking/zc.sharing integration that (as one integration  
option for zope.locking tokens) can filter so that only people with  
locks have edit privileges.  It seems to work pretty well, but it's  
also just one way to use the zope.locking tokens.  As with  
zope.app.locking, the "locks" themselves are purely advisory until  
you put in some code to make them enforced somehow.

zope.locking can do exclusive lock tokens, shared lock tokens, freeze  
tokens (effectively, no one gets the lock), and can also support  
custom tokens if you need them.
