I just discovered that bonobo-moniker-gzip uses
bonobo_moniker_use_extender - I guess that is the function I have been
looking for. 

Using this function lets bonobo-moniker-camera.c shrink to 39 lines -
the same would apply to bonobo-moniker-http.c. It really would be much
more convenient to make bonobo to look directly for "libstorage_hey.so"
when someone requests something like "hey:/whatever". This would save us
lots of helper programs like bonobo-moniker-http, bonobo-moniker-camera,
bonobo-moniker-ftp, and so on. Or am I missing something?

I have yet to get the extender stuff to work. "moniker-test -c
file:/home/lutz/image.jpeg" results in

** WARNING **: Attempt activate object satisfying
'bonobo:supported_mime_types.has ('image/jpeg') AND repo_ids.has
('IDL:Bonobo/Control:1.0') AND repo_ids.has
('IDL:Bonobo/PersistFile:1.0')': 0x8067cf0

and gives me the image back, whereas "moniker-test -c
camera://camera/image.jpeg" results in 

** WARNING **: Attempt activate object satisfying
'bonobo:supported_mime_types.has ('image/jpeg') AND repo_ids.has
('IDL:Bonobo/Control:1.0') AND repo_ids.has
(['IDL:Bonobo/PersistStream:1.0'])': (nil)

** WARNING **: Can't find object satisfying requirements

interface, too. I'll have a deeper look at it.
