Yes for sure. I think there's a way to use his whisper address and lightning box to self-host your own lightning address, serverless, and be able to send/receive at will

The brilliant thing is that its serverless, using only a key which the user would have when setting up their nostr.

It'd be like their first DM

Something like that maybe. Maybe even better if thought more deeply upon.
