It was tough turning all the synchronous asset resource requests into async ones. Not sure why this is a necessity for Chrome Packaged apps for local resources anyway. :-(
Is there any performance difference between the Chrome app and the original JS port? What are the benefits?
Potentially, raw socket access. This could be a server as well as a client. But I need to do some more work porting it.
