I don't believe that Subversion supports checkout-in-place.

...on the version. Yes, I think so.

Yes (in general).

It's version controlled if either checked-in or checked-out is set.

Well, there are multiple ways to do that. Check RFC3253.

Historic. DAV:getlastmodified is defined based on the HTTP last-modified 
header.

Dunno.
