I'd be happy to unblackhole mine if it gets more people involved. The x86_64 part is because ObjC doesn't provide a completely machine-abstract way to invoke dynamically. Each way has some icky flaws. My first goal was actually iOS, but I went down the x86_64 path because Mikael had a need for that first. I'd like the package to have x86_64/i386/arm. I did discover that a LOT more machinery is needed for x86_64 than for i386 or arm. Calling conventions on 64-bit are crazy insane (though I now have the worst of it solved).

Perhaps we should join our efforts... I propose the creation of a github repo specifically for this to share our codes. I know that Jason has his own repo (https://github.com/maitria/gambit-objc), but it seems to be based on blackhole and is x86-64 specific, and thus not usable on iOS.
I've created the (currently empty) repo
https://github.com/gambit-community/objc-bridge
for the purpose of putting together a portable and dynamic Objective-C bridge in pure Gambit Scheme. Who is interested in contributing?
