The Native Client source code repository is huge, but it is not that hard to find your way around in. I have been studying it because I plan to build something on top of it. I am by no means a stellar programmer, and I have found it reasonably navigable. (It did take me a few days to get my bearings, though, and I plan to use a much simpler, custom API to minimize the application's attack surface. Haven't looked much at Pepper.)

yes - but implement it in opera, ie, or firefox - you'll find that you've to rearchitecture a lot of your browser - or might as well just grab webkit (of course, in our case you can just try firefox since its the only open source one of the 3)

I must admit, I hadn't thought about the changes necessary in the browser. What major rearrangements does it require?
