*Update*
22 August 2010:
I have been in touch with flash developer @KarlFreeman tonight and while we were talking on Skype about the bottleneck of Flash Media Server he did some research and found the RedBox and Red5 open source Flash projects! See this post to learn more about Red5. Within a couple minutes we were using a RedBox demo of a video chat application, serving as a proof of concept that the only limitation to an open source platform for Junto is Java-ready server space!

It seems Big Blue Button is a Red5-based cousin of Super Cool School which could serve as the code base for the Junto platform.

The Junto project was presented at the August Mozilla Drumbeat Meetup in Berlin. The conversation with the attendees revealed issues with scaling the platform using Adobe code. Even though the Adobe SDK is open source, the media server software is only available for a paid license possible to replace with an open source alternative! The open source community will probably not want to support developing an open video platform for multi-channel telepresence on Flash technology.
How soon can we get an open source HTML5 video alternative? Is it worth building the next prototype in Flash to inspire the open source community to reverse engineer it? Some members of the open source community prefer identi.ca over Twitter, raising additional questions about an open video platform’s integration with API’s of closed-source third-party platforms.
Junto is a process but the platform that supports a Junto is a form; Junto is not necessarily software. The open video platform that could be built to support a Junto could also support numerous other open video business models. Berlin could become a center for open video development if the hacker community and film/video community come together.

As always, interesting points about Junto and its future. From the perspective of a flash developer the side of the fence I sit on is of course, open source flex but proprietary flash player delivering. In a perfect world, open source would be a viable route but the harsh reality is that with current technology Junto in a complete open source package is not possible, nor is it on the cusps of being able to compare to the users high standards of performance that proprietary solutions offer.
With regards to Junto’s integration with third party platforms closed or open, shouldn’t this be down to demand rather than ethos? I mean take for instance the identi.ca / twitter , you wouldn’t want to cut off either due to the sheer user base of either.
Some tough decisions here to solve for sure, but personally I think your spot on with Junto is a process but the platform that supports a Junto is a form; Maybe this should be the ethos that Junto takes on board with its views on open source / proprietary?
I’ve posted some thoughts on some of these questions. Looking forward to talking with you more about it!
