I have a v2.0 of the "Byron Deadwiler Paper". Is that up to date?

Regarding locking, smbfs can use the SMBlockingX stuff. It may not be
posix and it may not be fcntl, but it does seem to work. At least for some
simple cases.

Not really easier, but would allow it to do a better job for people
wanting to do linux-unix over smb.

I have looked at it before, but as the only server supporting it was HPs
samba version I never bothered doing anything with it. And it was not
clear to me that everyone liked them ... ;-)
(Long ago, things change)

I will start playing with it once support is in samba.
