Robert this is very interesting.. mainly because I wasn't aware there was
such a thing as a low latency kernel.  Guess with linux you are always
learning.  However, I have an experimental question.  Is it just the kernel
on the video transmitting side, the client/receiver side or both that the
low latency kernel has this impact?  Also, if the video server side is
linux with a low latency kernel then what would a client running x2go on a
mac or a windows 7 machine experience since neither utilize a linux kernel
?
   Thanks for sharing as I had always figured it was a latency problem but
I assumed it was 100% due to the network itself.
