On a side-note, I just wanted to share with you a conversation I had with a  mono hacker regarding the look of Mono on Mac OS X, even if in a somewhat twisted way for better reading :

Me > People are complaining it doesn't look "native".
She > Well, there are two answers for that:
Novell is currently concentrating on making Mono on the Mac a stable development platform. The System.Windows.Forms layer has support for theming and we could accept contributions for a Quartz theme that uses the HIToolbox APIs. Or, in a shorter version, we accept patches.

And then she said goodbye with the funniest tagline I've heard this week :"nothing like a linux forum to complain about how a windows technology looks on a mac"
