Your discussion of "real time video chat clients" has me cracking up; it seemed that a myriad of pieces of software had this figured out in the 2000s, but today I can't think of a single piece of software that I'd actually want to use for video chat. All of them have some fatal Achilles' Heel: Facetime has security problems/previously did not have group chats/is exclusive to Apple OSes, Skype is laggy and has more connection problems than any piece of software I've ever used, Google Hangouts chokes once you get to 3 or 4 participants and frequently has issues with even 2 participants, Duo is only usable on Android/iOS as far as I know... does anybody have a good client that they can actually recommend?

Myself, I've gone back to using Ventrilo because I realized that I really don't care about having video.
