this is an anti argument to me. you should be able to, over bluetooth. or maybe mdns, in some slightly better fantasy world. but this question distracts, picks foibled with airdrop, when a far greater scope question of why no one anywhere has low-intermediation direct device-to-device discovery. I don't care that Apple's implementation isnt perfect, doesn't work for xyz use case. no one else has any airdrop like basis at all. and there are no protocols or standards out there that begin to address this fault. everyone else is on square 0. terrible.
