Well, it worked from the end-user's perspective.

Well, no, this has been quite stable for the last revisions.

1) QTKit is a broken concept. Basically, you should implement it on your own, if you wish to use it in 3rd party apps. It doesn't make sense to use it through VLCKit. Additionally, you already stated that you won't support main thread handling through libvlc, so this argument is moot. Capturing stuff from the QTKit access modules within the ordinary VLC.app works correctly.
2) POSIX signal handling is blocked by the OS X ui. This isn't related to your changes and should be worked-out indeed. I'm aware of the trac ticket.
3) works for me.
4) works for me.
5) works for me.
6) I'm not aware of anything else either.

Yes, probably. I'll see if I can do anything.

So you are interested in breaking working code, but aren't in fixing it correctly so people can actually take benefit from your contribution? This is an interesting concept.
