Algo caster ideas 

Link Algo wallet and opt in
Coin with clawback enabled
Recast to claim airdrop
In app tipping via comments

Or possibly

Frame with that opens Pera for opt in

Cron job watching specific asset on chain, when it sees opt in with frame txn note it automatically airdrops coins to that wallet.

@fisherman curious on your thoughts— and how many devs might be needed
