How does videoconferencing work? Any limits on # of minutes or compatibility?

Videoconferencing is still in Beta. For now it is compatible with Chrome and Firefox or our desktop apps. For the moment it is not available on mobile. From any stream you can click on the camera icon and start a group videoconference with up to 5 simultaneous connections. We are offering unlimited minutes while it is in Beta. When officially launched you will have a certain number of shared minutes per month depending on whether you are on the Pro or Enterprise plan.
