Good plan.

Martin Wallmer said it well "'search arbiter' is an abstract term for a
piece of software".  It has no resource type.  But note that there is no 
requirement that the search arbiter be full WebDAV server.  Think of 
Google, imagine it implements DASL.

The spec should probably clarity this.

It should say it's out of scope.  Again, the situation is much like Google.

It is not easy to define, so we left it out.
you can not make it mandatory, since some servers are not willing to store 
results  even for a few minutes.
