Perhaps someone can clarify something for me.  I thought that Samba and 
NFS can't coexist.  I mean, obviously, you can run both servers at the 
same time.  But you can't export the same files with both Samba and 
NFS.   (Or mod_dav, god forbid.)

I remember the old days when you weren't even supposed to run local apps 
against exported filesystems, but that shouldn't be a problem with 
kernel-based servers.

The problem is caching and locking.  Kernel based servers will use the 
kernel's on pages so they shouldn't be a problem.  But can the 
userspace(?) samba server do the same?  Or does it have internal caching 
that can get out of step with the rest of the system?  (E.g., I know 
that mmap and advisory locks can go a long way.)
