Yeah, but it seems hard not to add anything. Objects not using it
could just return NULL, or have a NULL function pointer.

I don't know if this is good from a user-friendly point of view. I
think an empty menu is better, because then you see that something
happens when you press the middle button on an object, even if it
doesn't do anything for all objects.
Also it might be good to have some items from the normal menu also in
the object menu. Mainly place over/under.

It's not binary really it's just gzip:ed xml files. Try
'zcat samples/UML-demo.dia'.
