I've done some theoretical work on this. Email me off-list and I'll see what I've got.
Apple's documents on the Java/Objective-C bridge are required reading for this sort of thing.
I'm still convinced it's possible to inline Objective-C syntax into Dylan with some careful macrology. :-)

The Functional Objects C-FFI for Gwydion Dylan is progressing again. It might be worth concentrating on the Objective-C side of the equation whilst it's finished off. C-FFI is better than melange's C integration.
