For me, it'll be quicker to work with what's there already, trim it  
down to what we need, and tune it for Sugar (and specifically XO) use.  
Is there some FOSS political/religious baggage about forking like this  
that I've just trodden in? Or were you just hoping to engage upstream  
to do some of the work for Sugar support ;-)
