I was thinking we could add a "meta bug" to bugzilla (called "vlc doesn't
support codec/fileformat foo") witch contains a list of currently
unsupported codecs and fileformats, then each time people file a bugreport
on some missing codec we could close it as a duplicate of this meta bug, and
possibly the given codec as a comment to the meta bug if it wasn't there

There are also some things you missed.

speex - library available from xiph.org, sobody just need to use it.
fli/flc - old video codec, afaik ffmpeg can do the actual decoding, but we
          lack a demux.

I don't think it's the filters fault that it is slow, so you should probably
have a 
- improve video filter arcitechture
entry on your list.

agreed, I also think we should do a JACK (jackit.sf.net) aout.

BeOS and MacOSX allready did this move, I have a patch that works for
wxwindows on gtk1 and should work on unicode based wxwindowses as well. The
stuff that still needs to be looked at is stuff sent to the terminal (rc
interface and --help etc), the http interface( this should be easily fixed
with a http header ), the skins interface ( I don't know it's internals )
and the gtk/gnome interfaces (which I think needs to be ditched in favor of
wxwindows). To make this work everywhere I fear we have to explicitly link
with libiconv and export its functions to the plugins.

Otherwise, good work on this list.
