A marketplace is very much needed and can help with discovery for sure.

This brings up the need to handle different offering types.

- Physical goods transferred out of band

- Digital with links to retrieve

- Ongoing digital services with configurations and expirations.

Ongoing services like relays and file uploads need to offer "top-up" support to keep going, reminders of upcoming expiration, and the abilityforr people to buy and gift a service to others. Then who gets the reminder of expiration.. The gift giver or the recipient? Nuances to work out on that platform for sure
