  6 months ago it wasn't. I got it working pretty well over the winter
and early Spring. A friend is already using it for streaming video on
his web site. It's progress has been slower than I like cause I also
have to work on Gnash as well, support myself, that kind of thing. I'd
love to have somebody pitch in and work on it with me so it'll stop
being a solo project. Most of the code in Cygnal is shared with Gnash.

  I dislike Java too, which is one of the reasons I wrote Cygnal.

  The plan is to support multiple server side scripting languages like
python and PHP, in addition to ActionScript. This is the part I'm
working on now, as each scripting language runs as a separate process
that I communicate to using a socket.

 That's the plan, hopefully done by the end of summer. All the remoting
parts in both Gnash and Cygnal are working fine. Our twist will be that
we'll be using Celt, Speex, and Theora instead of NellyMoser and MPEG4
when talking to Gnash instead of Adobe.

  Other than it taking twice as long, it *is* better to implement both
server and client side at the same time. :-)

  You can see my the video of my talk on reverse engineering RTMP at
FOSDEM this year, to see how I like to do this. Wireshark has RTMP
support these days. What I did was take a pile of hex dumps I'd
captured, and turned them all into a giant testsuite. That way I didn't
need to use the Adobe plugin, which I'm too paranoid to even get close to.
