Rick:

OK. We will schedule the AG QoS demo at the times listed below. I will send
out an updated demo schdule as soon as I get confirmation about the change
in the Monday night schedule. Do you guys have any kind of abstract I could
get? I am putting together final press material and would like to make a
mention of this demo. The info needs to go to HPC Wire tomorrow.
