While rate limiting ICMP can be a good thing, it has to be done
carefully and probably can't be uniform across the backbone. (think of
a common site that gets pinged whenever someone wants to test to see
if their connection went down or if it's just loaded.. Limit ICMP into
them impropperly and lots of folks notice.) Such limiting also has to
undergo periodic tuning as traffic levels increase, traffic patterns
shift, and so forth.

Along these lines, how does this limiting affect akamai or other 'ping for
distance' type localization services? I'd think their data would get
somewhat skewed, right?
