  • You can't run your own signal server. All accounts use phone numbers in the same namespace as ID, and all messages go from the phone to opensystems.org, further on to google, and from google to the destination phone (with lots of encryption being added and removed at various points). This has advantages (it's difficult for the Man distinguish a received signal message from other android notifications) but also disadvantage (moxie can do traffic analysis and you can't do anything about it).
