+1 from me!
I asked this of Awesomium, which is similar to CEF, but not quite the same.
I suspect technologies like this are only likely to grow in use so if someone can get on board with them early, they'd be in a good position.
Awesomium modules are currently completely obscured to TC. All I can do with them is click co-ordinates. Which is a bit rubbish. Just means I have to do all my testing using Chrome and then we have to do a manual integration test of the Awesomium version. Depends how many hooks you have between the Awsomium module and your application as to how worthwhile this approach is ....
