Sorry, I'm not certain what you meant. Did you mean to say "I don't think
limelight has *ever* served HD content"? Or are you saying it has served it
in the past, but not now? Or?...

So when I've been excluding akamai and getting 1280x720 my stream has been
coming direct from Level3?

I got about 1/3rd of real time rate. i.e. it would take about three hours
to fetch an entire 1 hour 1280x720 program. Are you saying that is a "good
speed"? Or are you saying the slooow rate I got was anomalous and I should
try again a few times to see if I was 'unlucky' when I tested this?

OK, that's useful. It means I can focus on the other issues above and not
worry about my currently using 2.93.
