Thanks, I found that to be a useful summary of the issues and to have some
good pointers.   I'd like to add one potential work item, though, before
"define best practices for performance evaluation":  "describe what a
useful lab setup would look like".  Looking back at our own experience at
building a lab, it strike me that we have many of the elements you describe
but lack one:  we have multiple, heterogeneous networks in a variety of
topologies, but we also have a single higher-order administration.  So we
may actually be scheduling away some of the real-world implications by
parceling out project activity in the lab.

Thoughts on how to avoid that from the group would make a good addition
(either to your doc or to the best practices doc).

regards,

Ted
