Ah okay, is that where the NIP100 bit comes in? If communication can be established over general relays then the app isn't dependent on you guys running specific relays?  

 Yes, exactly! The app doesn't depend on us running specific relays. This gives you the flexibility to use other relays or even set up your own if you prefer.  

 Damn...this is awesome. Truly amazing work. I really can't help but wonder if this would be a way to go about doing away with a phone number all together.
