Yes. I think that's the entire point. Things like games and autocad have enormous codebases that will never be ported to javascript.
It's still not clear how much an advantage that is though. You can already share assets via the network while still using a local native application.
Pretty sure this is part of their ChromeOS strategy. It would be impressive and a big differentiator for a tablet (presumably an x86 tablet will exist at some point) to be able to run srs bzn programs.
