I suppose I could wait until you land the patches and see by myself, but:

- In the wiki you mention that one goal of the new framework is to
provide a stable C-based API. Is this meant as a public API for
WebKit, the same in all platforms (like JSC), or a stable internal API
for embedders to use in order to implement their native APIs on top?
>From some lines in the wiki (like WKView wrapping native objects) it
seems like you want to do the former, but that seems like quite a
massive effort and the loss of an important selling port of the
various WebKit ports.

- Does your new framework require any significant changes in WebCore?
Could you briefly summarize them?

- Do you see valid usecases in the long term for the "traditional"
ports or are your plans to quickly transition all code to the new
system as soon as it's ready?
