Initial drafting

 * Must be reasonably self hostable. I say reasonably because Signal advocates will often say you can *technically* self host Signal, if you "simply" modify away the Twilio dependencies, modify the clients to connect to your server and distribute your client to all of your contacts, etc.
 * Closely tied to the last point, it must support federation. Self hosting without federation can work, but isn't particularly useful at scale.
 * Good mobile support with proper offline message archiving, instant notifications, etc
+* Must not require [KYC](https://kycnot.me/about#what-is-kyc) to sign up
 
 Despite these requirements, I will still go into detail about some of the options that were ruled out, in case you aren't as rigid on these requirements as I am.
