does anyone know the latency range of this type of update? If you are
using the clock on the backend, and updating the image on the client,
then there would be  an unknown latency here -- or is it unknown? Maybe
there is a "probable" range that can be counted on?

Here's another related question. Say I want to send an audio stream to a
client and at some point the user clicks a button to switch to a
different stream. There will be latency that is the sum of the latency
of all the hops (and server and client latency, which would be much
smaller) that the user request path takes and then the latency of the
new stream. Can this be determined dynamically?  Is there a rule of
thumb for a range, or worst case?
