     I don't understand the congestion argument, so please help me 

     What will happen if we start at 3MBit, versus slowly increasing 
bandwidth usage up to 3Mbit in the following cases?

 1. The pipe is a synchronous 2MBit line
 2. The pipe is a synchronous 4MBit line

     For case #1, if the initial fence is minBandwidth = 3MBit, I expect 
the callback to get invoked right away and it either aborting the 
application or reducing the video resolution and minimum bandwidth. In 
the case of a gradual ramp-up, I expect the same end-result (callback 
getting invoked) but it will take longer to occur and will take place at 
the 2MBit mark.
     For case #2, I expect both scenarios (immediate vs ramp-up) to be 

     Did I miss anything?
