It would be great if there was native Chrome OS support. The Android App on some Chrome OS devices is OK, but there is a layer of emulation there. A native Chrome OS extension would give a better experience.
It would be nice if instead of downloading the daemon on every computer you want to play on, you could just get a chrome extension and then play games in-browser. Or maybe, parsec could just run in html5, whichever one is easier. I don't know how difficult these would be to program, but i hope it would be easy to implement.
