- Adobe Flash (by means of OpenLaszlo) and open source projects compliant with current Apache
policy.
+ Adobe Flash (by means of !OpenLaszlo) and open source projects compliant with current Apache
policy. The UI code is compiled by using !OpenLaszlo, not by using Adobe products. !OpenLaszlo
is licenced under the CPL. !OpenLaszlo's concept is that you write the code in a XML based
approach, it is possible to compile the output to Flash or DHTML/HTML5. So on the long run
it might be possible to replace the Flash UI with a DHTML one. But as there is little multimedia
support in HTML5 especially for Webcam and Microphone access it is not possible yet to prevent
using Flash in general. The needed Real-Time Communication could be done using Ajax and HTTP-Push
mechanisms like Comet instead of AMF which is currently used.

- There is an alternative implemenation that we've done using an Java Applet that uses SIP
acting like a softphone and that does not need Red5 for Streaming. This implementation is
not in production yet and you need additionally a SIP Server that does the necessary conference
calls. But we have done conference calls in cooperation with a Finish VoIP Provider.
