The capplet should be set to "Guess my audio environment", seeing which 
audio output plugins are available on the platform, then trying them out 
one-by-one, moving the previous success to the top of the list.

No, it actually shouldn't be needed to run gstreamer-register by hand at 
all. I guess that it should be part of the gst_init().
  If the user doesn't have write access on the global registry, write a 
user-wide cache.

Yes, things like which decoder/encoder to prefer when there are multiple 
ones available for a media-type: "mpgparse ! mpg123 or mad for mp3 output ?"

The capplet is just an application like any other. The few dependencies 
would be glib and xml. You can't do much less.

I don't think this is needed. These are preferences, not settings (ie. 
they can't be wrong). And you would add GConf, OAF (iirc) and Orbit 
dependencies on your backend ;)

Martin has actually setup CSL to be used only as a module. We just (sic) 
need to write such a module that uses GStreamer instead of CSL.

With nice icons ;)

I guess these 2 go together.

Well, I don't know how Steve's architecture for mozstreamer is, but it 
seems like it could be a wrapped-bonobo componenent. Mind you that I 
don't know anything about how to write a Mozilla plugin.
