I suppose it would depend on hardware limitations. As far as I remember, Airdrop on OS X also requires specific hardware for the WiFi connection, only found in 2008+ Macs. It could be that a similar connection is possible between Macs and iOS devices, again, supposing that the hardware allows it. Even if that would not be possible, is it then not possible to find a workaround using WiFi? You can already sync your iOS device over WiFi with your Mac, so it should be possible at least indirectly. Regardless, this is Apple's problem to solve, since they are the ones creating the confusion in the first place.
Considering the variability of my luck with getting this to work, I'd imagine using Airdrop would be unbearable.
