Yes. The name= option is a UID for each peer. Also regex is very very
slow. dstdomain is better for those ACL.

Good idea. They are already done loosely that way for selection methods,
but there does not appear to be anything to group peers based on a tag,
and certainly nothing to group *_access lines together yet.

Want to spec out a 'pool=' option for squid?

Problems:
 How should a group with mixed selection methods be handled?
 How should specific per-peer ACL affect peer group ACL?
