The big difference between libswfdec and libswfdec-gtk is that
libswfdec itself does not require a main loop. All stuff that does
require a main loop goes into libswfdec-gtk. This is slightly
unfortunate because there's various projects that do use glib main
loops but don't use Gtk, but splitting Gtk into two libraries sounds
stupid too. And I don't want to have Swfdec support main loops, or KDE
people will start to look at me funny.
So far I've just copy-pasted the files from libswfdec-gtk that I
wanted to use, if I couldn't use swfdec-gtk. As libswfdec-gtk only
uses the public API of swfdec, that is easily possible.

Yes, Swfdec supports this fine. As I said above, libswfdec-gtk uses
only the public API of libswfdec. So you can take the libsoup loader
and replace the calls with curl calls and it'll compile fine. (As a
ide note, the Mozilla plugin implements their own loader, too.

I do think it's a bad idea. Only backends that get regularly used are
able to keep up with our development. Because of this, we try very
hard to only have one backend for everything and drop everything else.
See the recent discussions when we dropped support for ffmpeg, mad or
oss.
Of course we support other people writing and maintaining their own backends.

Should be fixed in git (and 0.6.8 when we release it).

See http://swfdec.freedesktop.org/documentation/swfdec/swfdec-Enumerations-and-Types.html#SwfdecKey
I've fixed the docs in git, too.
