Screen and audio streaming using one connection/one client

[Sonia SWEngineer]

This is a general question regarding the capability of the streaming
technology with red5 server.  I see OpenMeeting uses two
connections/clients to stream audio/video and user screen.:
Client 1- the parent client captures and streams audio/video
Client 2-  captures and streams the user screen.
Is it possible using red5 server to stream screen and audio/video using
just one connection/one client?

Thanks!
