(I installed ring long ago and tried it out a bit, but never really used it.)
With jami showing up in f-droid, I tried it out and have some usability/doc comments. * There is no option to not set up a ring account when starting the app. Presumably I should be able to import one from another device, somehow. Or, I might want to be able to configure SIP, but not ring. So it seems there should be a "skip" button. (Yes, I realize I can create and delete.) * There is a notion of an account name and thus presumably some sort of global name->pubkey hash. The user is prompted for this, but no guidance is provided (or linked to) about privacy implications of this. * The app seems to be configured to use a proxy instead of direct DHT access by default. I couldn't find an explanation on jami.net about why that choice was made, or about the privacy issues surrounding DHT registration. * On jami.net I cannot find a privacy policy about the proxy. Obviously it ought to keep no logs at all, and merely the current session in RAM, and not disclose any data to anyone. But it doesn't say that. * The FAQ does not explain if the SIP client does ZRTP. * There are pretty clearly going to be firewall traversal issues. I didn't find anything about that. * On the site "The Free Software community advises and recommends using Jami with GNU/Linux." is a bit much. No one speaks for the coalition! * Overall, it seems that there needs to be a user manual. Perhaps one would suffice as the UI for settings is semi-obvious and it's the semantics and plan that are not clear. * is ring@gnu.org the same thing as r...@lists.savoirfairelinux.net?
