If you can make the virtual devices look like ethernet, I believe a lot of other things will just work w/out hacking, including user-space apps that think they know exactly what an ethernet frame/device looks like. The only things I think of that won't work like ethernet is the ability to change the local MAC address or go into promisc mode. And, it's always possible that future wifi hardware will support that as well. Either way, the current API handles this fine: the requests to change will just fail with a convenient error.
