I haven't used it enough to give a good response to your question.
I've played with AppEngine, which also doesn't support joins.  And
I've been programming long enough to have used file based database
managers -- ala btrieve type mechanisms which didn't have or enforce
relational concepts -- so, I don't think the mental leap is going to
be noticeable.  However, the CouchDB people will be the first to tell
you that CouchDB is not a replacement for relational databases.  So
not all problem domains fit within the scope of the project.

Currently my mental picture of CouchDB is along the lines of BeFS -
http://en.wikipedia.org/wiki/Be_File_System . This is a poor picture
as Couch is both more and less but both share many of the same
attributes, that are important to me for the current project.
Extended Meta data, ability to query on that meta data in an ad hoc
fashion and extremely short recovery time in the event of power loss.

Have you used Bzr + svn with this plugin?  How different did you find
the commands?
Ok, now that was a dumb question after I googled and discovered your
connection with Canonical.

Too bad Des Moines is 2 hours away, makes coming to meetings a non-starter.<g>
