If I read this correctly, you have refactored WebKit into an embeddable layout engine that can composite offscreen. It includes the javascript engine so it is able to render browser shots better. You also can send this bitmap to a 3D pipeline.
The selling point needs to be brought to the fore. While Internet Explorer is embeddable, it doesn't offer as good HTML5 compliance as webkit.
Our first draft of the site was actually very heavy on the tech details but we ended up trying to dumb it down a bit to appeal to a wider audience. It's tough trying to find a good balance between the two.
Have you had a go at building Android Webkit for running on PCs? It'll be a lot more useful than using the Android emulator for testing web layout.
This has been packaged as SDKs for both Windows & Mac.
