This is amazing work. I hope it continues to go even further. I'd like to see a browser that is really just implemented on top of a kernel with full programmatic access to everything from the top down: just as Emacs happens to be a text editor built on the elisp kernel, Firefox could happen to be a browser built on a web kernel.

Everything that drives the UI are just functions that could just as easily be invoked from the scratch pad. If you know a bit of javascript you can write a few of your own functions to automate some common browsing tasks. And if you need even more functionality you can dig deeper and write your own libraries that seamlessly integrate into the kernel without a hitch and can be invoked from your own menus.

No plugin tom-foolery or artificial walls around the garden.

Looking forward to seeing how this develops!

You are pretty much describing the Firefox architecture. We are invoking Firefox UI code from scratchpad all the time when prototyping things. Some parts of the UI do not use standard Web APIs (e.g. XUL and XBL), as there are different opinions on how the web platform should evolve to fulfill those needs, but if you include all the experimental technologies to this web kernel, we are already there.
