Hi, this is possible today!

You can create isolated app connections from your hub and give them to other users - these are basically subaccounts.

The users can then add the connection string to their own Alby account to have their own lightning address, or connect it to the Alby Extension, or Alby Go (new mobile app coming out soon)

We'll have a dedicated "Friends & Family" app for this in 1.7.0.

If you'd like to create many users, there is also an experimental app: https://github.com/getAlby/jim
