A real 3d-enabled web browser for WPF?

I know, some of you think that the browser control in the latest WPF 3.5 SP1 is the dog's bollocks. Sadly, it suffers from its origin as a wrapper around good old GDI and the lack of GDI redirection imposed by supporting WPF in Windows XP environments.

One thing I keep track of very closely is what the mono guys do. This is a fantastic pool of resources, skills and code, and if I had time to hack I'd probably join one of their many projects. And on their feed I came across Alp's post describing a WebKit-based 3d web browser. I can't wait to have a play with the code.
