Hey Alex Cohn, thanks for your response and for trying out Fam, really appreciate it! Yes, you are correct that you can use the iMessage extension without registration. It is possible to do what you suggested, and in fact that was Fam’s initial version when we launched back in December, 2016. We quickly found that it would be best to bundle the extension with a home screen app to offer users the ability to use Fam while in background mode (cannot do that with iMessage extension) and for other home screen app rich features. We do plan on using Safari’s WebRTC functionality for when Fam scales to other messaging platforms.
