  Actually this is the right way to do it, because I have a patch to
libCurl (http://www.welcomehome.org/gnash/curl-080206.tar.bz2) that's
about 90% done to add RTMP support. There is a bug in the AMF header
encoding I haven't had time to track down. So we need to use libCurl to
handle talking to a Flash server. We may still want to use the
background thread and a cache though.

  Probably correct again.

  We should make a base class for this just like the networking code is
for NetConnection. Supporting multiple decoders is also a good idea. For
one thing for better Nokia 770 support, they donated patches to
Gstreamer for their hardware based video decoder. Since ffmpeg has FLV
and VP6 support, we'll need to potentially use the ffmpeg Gstreamer
plugin on some platforms to get better performance.

  Yes, since we'll be wanting to stream video on embedded devices, which
is when we'll likely be using AGG. The Cairo backend isn't fully
functional, I don't think anybody's been working on it since the AGG
backend works.

  You'd think that would be easier, since there is no networking required.
