Interesting - do you mean using the Android handler/message infrastructure? I hadn't considered that at all. Do you have any references?

Yes.

One example would be SDL, although they use a mix of JNI and messages (search for SDLCommandHandler).

EDIT: Sorry forgot about the C side (counterpart is Android_JNI_SendMessage).
