  Thanks for your response; my comments are inline.

Yes, I had thought about AppleEvents as well, but I'm trying hard to eliminate Carbon.  Nevertheless, thanks for the concrete example.

I did not try it with the application not open.  I believe the application gains focus because of the CFBundleURLTypes key in the Info.plist.

Regardless, I've figured out why it isn't working.  Unfortunately, I'd need to run the NSApp mainloop from pyObjC for this NSURLProtocol handler to receive events.  I suppose it could be done within another thread, but then I'd have to use gtk.gdk.threads, which seem to block at application exit on Mac OS.

Further, I don't think it should be necessary to execute the mainloop from two application frameworks to make this happen.

If you're reading this, John, any chance we could get a method in OSXApplication to install a handler for NSURLProtocol?

I thought I did, but I guess I didn't.  Output definitely goes there.  Thanks for reminding me.
