Is there anything in Linux that implements whatever it is that makes Airdrop in OS X work? I'm not really familiar with that program, so I'm not sure what protocol it's using to communicate. *update* Specifically I'm looking for a program(s) that if I fired them up, I'd be able to receive and send files to an OS X machine, like I was using Airdrop. (this may be like needing samba to network with windows)
