Yes, and the Android NDK allows you to write arbitrary C code, it's
just a slightly less than pleasant interface with the SDK :-(.
Perhaps it's easier to do this in iOS as it's all objective C rather
than a vm with a runtime system. Also not sure what the status of
porting the runtime system to ios would be.
