Oracle appears to be a victim since they were planning on integrating their own JS engine into webkit.

Apple's webkit looks like it will only support JSC

I would be surprised if chromium decide to support anything but V8

Oracle might need to maintain their own fork of either webkit or blink just to support their JS Engine.

Chromium (kind-of) supports DartVM. The fact that they're working on Dart will be a big incentive to keep the abstractions between the browser and the scripting language implementations as clean as possible.

Now that is a very good point.

So while webkit is most likely a no-no blink may be possibility for Oracle.
