With regard to screen space logistics, we've developed a version of  
vic that does DV and HDV - full details and perhaps a demo at the  
forthcoming AG Retreat. One of the changes is the ability to resize  
the video window(s) to any size you like. Thus you could accomodate  
several streams at smaller than true HD size when display space  
becomes tight.

BTW, I think that when DV, HDV, HD are all more common in the AG,  
best practice will be to always send those formats as duplicates of  
standard H261 streams so that other sites can choose to view their  
own preferred mix of H261 and higher resolution formats (somewhat  
avoiding the screen real estate problem you raised, not to mention  
bandwidth issues). The cameras we've been testing with have a number  
of simultaneous outputs available so its trivial to send both DV/HDV  
and H261 at the same time.
