Nice solution! I especially like that if this Squid is configured to use
SMP-aware caching, then other peers can use just one of the worker ICP
ports to send queries to this Squid (if they need to query it at all) --
no need to query each worker individually.

Amos and I have adjusted documentation at
http://wiki.squid-cache.org/Features/SmpScale to reflect some of this.
More development work is needed to make ICP work better so that this
workaround is not needed.

Thank you,

Alex.
