  No, not yet. The client side code currently lives in a standalone 
utility I haven't checked in yet.

  Not yet, but Gnash will use these when the reverse engineering phase 
is done. Cygnal does use these files, and they're designed to be shared 
between cygnal and gnash.

  Currently flv playback "youtube" style uses HTTP for transport, not 
RTMP. My RTMP hacking is mostly all done, so pretty soon the work to 
merge it into Gnash will start.

  No, Gnash handles it internally. gst/ffmpeg are only used for 
decoding, etc...

  Because there were no free RTMP libraries, and now there are. :-) 
Neither ffmpeg nor gst support RTMP.

  Curl changed it's internal API, so my RTMP in curl code broke. Rather 
than fix it, I rewrote it to support the server side as well.

  Try this link, where I've been adding docs on RTMP:
