Questions and Comments:
Is the PERT concept something we could implement here in the US?
Argument in 2001 was that "we don't have the tools." But now we do have them.
It would be great to add this human network.
USAtlas has perfSONAR and is starting to take measurements. But when we have problems, how do we isolate them?
