I would like to work on adapting the overloaded slot resolution code in 
QtScript so that it can work with overloaded smoke methods (I think it might 
be useful for QtRuby too). So if you can add me to the committers for the 
group. Or should I get added to the kde-developers group - is that better - 
but i've read about gitorious spamming people with unwanted commit mails?

I think this is a very good project from the point of view of raising the 
visibility of the smoke language bindings because we have something that we 
will be able to directly compare to an existing project. It will demonstrate 
that we can use much less memory resources that other approaches.

At the moment all the major Qt modules are in a single libsmokeqt library, and 
maybe we could split that up so that you only get the ones you need. But the 
GUI module is so much bigger than the others, I'm not sure if it would make 
much difference.
