It is totally possible. I created a prototype about 3 years ago to try
to mimic Chrome's multi-process rendering, the code is here:
https://github.com/leavengood/Haiku-Browser/tree/master
Basically RenderBoy is the rendering process and the main browser
process has a ProxyView which forwards mouse moves and clicks to the
render process. The render process draws into a bitmap and sends the
bitmap data to the browser process which displays it in the ProxyView.
I don't know if the design is perfect by any means and I'm sure it
could use a lot of clean-up and optimizing, but it does work.
I imagine you could download that code and still build it with Jam to
try it out.
Extracting that into a more generic BRemoteView would be nice. I don't
know if I have the time to help, but if you do make that please send
the code back my way, or send a patch so we could maybe put it in
Haiku's shared kit.
