Anyone know if they're using the JS-based renderer, or is this C/C++-level code?

Probably C++. A quick Google Code Search on the Chromium project reveals files like this one: http://codesearch.google.com/codesearch/p?hl=en#OAMlx_jo-ck/...

I'm not 100% sure that's relevant code to the discussion at hand, but it seems likely.

It's C++. AFAIK it's built on top of the Foxit SDK.

I can confirm that there were foxit references in pre-beta source code

edit: i think this was the reference i was thinking of, is it for this feature, or is it unrelated?

On Ubuntu if I go to chrome://plugins it says:

/opt/google/chrome/libpdf.so

Is that foxit SDK?
