Very nice. I'd be very happy to lend support.

This is what we do at Archimedes all the time, so it works. The only  
issue is that we maintain the windows build system in-house here and  
don't publish/support windows officially. Nick Hebner used to maintain  
a windows build, but I don't know if it's current.

The c-base demos are not always in sync with current svn, so maybe  
you're not running into windows issues but general version  
incompatibility stuff - what goes wrong? (As always: Traceback, os &  
video drivers used, svn rev or release used,... help in determining  
what's going on.)

That's a wishlist item., but there's a clear path to implementing it  
using LLMozLib (http://www.ubrowser.com/). The html should be rendered  
into a texture, so you have full compositing (alpha channels, scaling,  
distortion,...) available for the pages.

Cheers,
