Does the Flash Player support Apple's HTTP Live Streaming protocol? If so, where is that documented? If not, does anyone know if support is planned?
No, at this time Flash Player doesn't support HLS, but if you are interested in it try to look at http://code.google.com/p/apple-http-osmf/
...It's a free (MPL) AS3 library which adds support for Apple HTTP Live Streaming (HLS) to OSMF!
