Hi,
 Steve - you must be kidding - surely ?

I thought the whole purpose of a jitter buffer is to 
  a) smooth out the rate at which packets are received, 
  b)reorder packets if necessary
  c)cope with lost packets

 Now, since you have no control over 
  a)how long a packet will take to travel from the transmitter 
         to the receiver
  b)if packets will be reordered in transit
  b)if packets are lost in transt,

placing a jitter buffer at the sending end seems a bit pointless.

Derek.
