At this moment you would need lounge indeed. Unfortunately, there isn't
really good documentation on how it actually works and why it works like
that. There is, however, documentation on how to install the several
components.

At this moment, documentation is still spread between the github and
google code. Perhaps now would be a good moment to invest some additional
time and add documentation which i'd prefer to put on CouchDB's own wiki
instead, but i'm unsure if the contributers will be very happy with that.

At least, it works quite well and you can ask about it on this
mailinglist, there is no other public place to discuss at this moment.
