I had an idea - base k-meleon on the winembed version of mozilla.
With a gui change, the browser will have many little bugs of his own, and it will always be up to date with the mozilla build.

I'm using it now. It's kinda stable and fast too..
I've also noticed that mozilla renders the pages ALOT quicker than ie does.
Way to go mozilla...
Please respond, especialy the developers, who knows if it can be done..
