@jamalex I'm going to (temporarily) close this branch shortly, but one important thing we need is scripts that automatically set up a central server for servicing JSONP requests.  This has blocked testing not only of this pull request, but others as well.

Looks like you were able to get things working on the actual central server--great!  Can you use what you learned there to set this up through Python, for any central server?  not only would it remove this "temp" issue here (which personally makes me cringe, not unlike how my modifications of django did for you :) ), but would allow any dev (including @ruimalheiro @dylanjbarth and myself) to develop and test using JSONP (which, in fact, we're trying to do now).

Feel free to comment while the pull request is closed.  Lacking the ability to do cross-domain JSONP is a blocking issue for the software updates feature that I'm working on, as well as @dylanjbarth 's latest work on subtitles.

Thanks!
