My guess is not so optimistic. # of real rust programmers is low. If integrating Firefox with Servo means having 1 small part of Firefox integrated with Servo, mabye, a month of work? But the entire Firefox render engine with Servo will probably be at least 5 years away. While 5 years seems a long time, don't forget time fly and bug blockers come up.

It's been stated before that Servo may get a Webkit-compatible interface, meaning you should be able to build a Chromium with Servo pretty easily, and far before it would take to integrate Servo into Firefox.

I'm not sure if that's still the plan, however.

Does Webkit have a very large API/ABI surface? This seems like a nightmare to implement correctly and maintain.

I have no idea.
