I'm using a whatsapp-group to keep in touch with other developers in the same project. That's sub-optimal in the sense:

1. Data is owned by another company (and we don't know how secure that is).
2. It does not render phabricator assets (e.g. {D123}, {F456}).
3. It is yet another place to book keep members (e.g. dev is no longer part of the project, need to remove it).
4. Lacks support for desktop (I heard there is a Windows client).

OTHO, it is a great app:

1. Available in many mobile platforms.
2. Easy to use and reliable.
3. Hassle-free management.

How hard would it be to have such thing in Phabricator? Say, through IRC or XMPP? Ideally it would:

1. Provide same whatsapp experience (persistent chat rooms, easy to use, available in many platforms).
2. Member management through phabricator Projects.
3. Render Phabricator assets.
