   By "in-place editing" I mean that when the VCR is checked out,
clients can

   checking in.  In the meantime, this work-in-progress is available for
   users to see if they have permission to read the resource.

   First question: Does anybody plan to implement DeltaV this way?

I would strongly consider this an option, if a default GET and PROPFIND
did not reference the work in progress but instead referenced the

Imagine this:
After checkout, GET/PROPFIND from users that don't have the resource
checked out refer to the last checked in copy.  PUT/PROPPATCH are

For the user with the resource checked out, all operations apply to the
checkout-in-place copy.

That gives you most of the functionality of the working resource model,
avoids things like UPDATE/MERGE interactions with working resources, and
avoids placing extra demands on the client.

If we weren't trying to be compatible with a 3rd party DAV + revision
but not DeltaV server, I'd propose that we do it this way.  The 3rd
party server puts the working resource in an independent namespace.

CA and I work in WA where it is cheaper to live.  We have independent
