Forum OpenACS Q&A: Integration of conferencing tools in oacs/dotlrn?

Has anyone integrated a conferencing tools with oacs/dotlrn?

Today I looked at adove connect (formerly breeze) and it is really nice and was wondering if there are open source solutions similar and if someone successfully integrated it with oacs/dotlrn.

Background:

Adobe connect is very similar to dotlrn and provides many applets:
- video & audio conferencing
- layouts just like portlets in dotlrn/xowiki
- shared whiteboards
- display of a remote desktop or application window
- shared files
- assessment
- chat
- recording of conferences and export to AICC/SCORM
...

It is a conferencing/groupware/community solution and completely flash based.

Off the topic: What is really nice with adobe connect are the layouts. Depending on the situation you can define different layouts for your community. During the lecture you rather display the powerpoint presentation and video while during questions and answer you display the video , chat and a white board.
