off the top of my head, it would seem the loaders should advertise
which mime types they can load, and then gdk-pixbuf asks gnome-vfs
"what type of file is this?" and then invokes the proper launcher.

sadly in reality this won't happen, as gdk-pixbuf is in gtk and
probably won't be able to depend on gnome-vfs.

eog could generate the list of mime types it supports at build time, by
querying gtk (this could even be a perl script, possibly) and build its
oaf/vfs config files this way.

but if gdk-pixbuf could have 3rd party plugins (xcf comes to mind) then
this seems like a harder problem - which will probably come up in some
other application (gnumeric?).

i don't have any ideas on this problem, though.
