video chat button from messenger: have a little IM box come up "(member) wants to video chat"
when someone presses the video chat button on the person's profile from messenger, have a little IM box come up on the bottom of the screen or something that let's the person know instantly. For example, "(member) wants to video chat. Accept / Decline."
We will add IM Video chat in future version. At present there is group chat option.
Anyone who has access to the Profile page and Video Chat button can start Conference, in this case the all friends of the profile get notifications about just started Video Chat and can open profile page and join to the talk.
