Jeff:
 
The timing synchronization relationships in smil are independent of what
viewport media may be playing in. All timing and scheduling markup used to
synchonize media applies wether the media is shown in the same or different
viewports.
So SMIL 2.0 supports that you ask for directly.

Subject: Multi-Channel Synchronization


 
We are building a very specialized multimedia "player" and we are trying to
use SMIL to schedule it. 
 
Our "player" has multiple output "channels" for media presentations. Each
"channel" has its own 
independent output window. So our "channel" entity sounds like a SMIL
"viewport".
 
We need the ability to synchronize the play of media files across multiple
"viewports".  
 
For example, the play of video3.mpg on viewport #1 should be synchronized
with the play of video5.mpg
on viewport #2. 
 
Some sections of a presentation maybe be synchronized and other sections may
be completely 
independent. 
 
Is there a SMIL 2.0 recommendation that addresses this requirement? 
 
Also, we hoped to use independent SMIL documents to schedule each viewport
when media synchronization
is not required. We would use one SMIL document when synchronization across
viewports is required. 
 
Is there a SMIL 2.0 recommendation that addresses this requirement?
