If you just said 'yes', you want something Adobe is working on, not even in private beta yet, code named 'CoCoMo'.
CoCoMo will be a set of components, as well as source code, for the foundation classes Adobe used to build the next version of Connect Meeting - it includes both high level components like 'webcam' or 'whiteboard' as well as low level 'a/v stream manager', 'connection manager' etc. etc.
Or you can use it to build add-on pods to Connect Meeting (in the 'Pro' on-site version).
Permissions and role management are all built in too.
t will allow you to add real-time chat, VoIP, web cam etc. etc. straight into any Flex 2 or Flex 3 app. Or you can build your own version of Meeting.
All in three MXML tags (and one of those is mx:Application !). It's 15 lines to build a shared whiteboard with web cams for all the collaborators.
This stuff is bonkers easy.
You don't need to write any server-side code. You just use Adobe Magic Server (name and what it comes with currently undecided).
But that's a pain right ? Who wants to run another server ? So Adobe will be hosting these servers ! There will be some level of free offering there for apps that don't use much bandwidth.
Later you'll be able to deploy your own server for CoCoMo (maybe in ColdFusion 9 I hope).
Talk about low barrier to entry, this is great !
CoCoMo is all built on top of the XMPP (xml) open standard. Or it will be once it's finished.
It all works in AIR as well as Flex which is where the title of the post comes from.
The CoCoMo Blog is http://blogs.adobe.com/collabmethods, and an online presentation is at https://admin.adobe.acrobat.com/_a300965365/p86262461/. View the preso. for code samples, a look at the next Connect they built with CoCoMo and more.
They'll be a private beta by end of year, fingers crossed.
As a last thought, remember you can have a 'connect to online meeting' button in your (say) invoice PDF. And now that button on the invoice can connect the customer right into a nicely branded room with your credit control team or whatever.
