Can you elaborate?

I’m thinking about using it as a broker for a little family-group oriented word game, because the servers that do what I need already exist and include the NIPs I’d want, and truly, Nostr servers have been the simplest, least resource demanding servers I’ve run. There are copious libraries in every language for writing clients. It seems ideal.

I’m not concerned about scaling, but I am curious about what those issues are, as I haven’t heard of any.
