It just happened that way.  We started out with an INI style config
for the perl stuff (before the C bits were written) because I had
built an advanced INI reader/writer in a previous life
(nested/cascading structures, typed values, #include files, magic OO
interface, etc).  It proved a bit tricky to port everything to C, so
we just went with the low hanging fruit of XML.

That's on the roadmap, for sure.

And that sounds as much like an offer as we'll ever get! ;)

You can take a look at http://ln-s.net/GZs (Web CVS repo) to see what
we're doing now.  We'll need to keep things API compatible since we
use the O::U::Config interface extensively in the perl innards, but
it's certainly doable, I think.

We already use XML::LibXML in the perl stuff, so that's the
natural/prefered choice for the XML parser, but we do have a
dependancy on XML::Simple for some outlying pieces, so if that
simplifies things then it would be acceptable as well.
