Julian, Stefan, and I had a side thread on the question of
Microsoft IIS support for lock-null resources.  I figured
its results might be of general interest.  Summary:

IIS does allow you to issue a LOCK against a null resource,
but it does not create a lock-null resource as defined by
WebDAV -- it just creates an empty file and locks it.

Cheers,
Geoff

Update: MKCOL on an IIS lock-null resource gives 405 NOT ALLOWED.
So, IIS internally creates an empty file and does not know about
lock-null resources.
