Neither am I! Figuring out what it can solve and what it can't is on the
table.

That's going to take quite some time, I think. Title of email was

"The challenge". Next up is extensive real world tests and tweaking, more
simulation, varied workloads.

Ah. Lost in the footnotes. You mean redlight?

The link on the acm queue to:

http://www.cnaf.infn.it/~ferrari/papers/ispn/red_light_9_30.pdf is busted.

We have a link to a mirror of that here:
