Yes, I'm thinking of offering various set-ups in the future, if I see that people are interested

Make it timing based and randomized. Sync the 'seed' during device init, and then the listener knows when to listen for the airtag. The airtag then turns on for a specified duration (random between some min/max time), and the listener picks it up.

Bonus points if the 'seed' is volatile.
