Yeah, unfortunately our documentation is in a really sorry state.  The
actual project you want is wvstreams
(http://code.google.com/p/wvstreams) which is used by versaplex.
wvdbusd definitely works standalone and the code is much easier to
work with than dbus-daemon -- if you like C++, that is.

The XML is a bit of a strangeness, when the dbus message/struct format
was already a perfectly good way to encode things.  But that's how it
is.  In any case, there are already tools for browsing a bus and
parsing the XML and calling things; all you need to provide is the
system to bridge the buses together and proxy messages back and forth,
and the method/object level stuff is handled already.

Have fun,
