Hi Art, Less ISPs than mobile carriers (e.g. T-Mobile) where the operator has substantial control over the subscriber's CPE and can require the presence of a CLAT client for 464XLAT. The key challenge (and key cost driver) with v6-only eyeball networks is the wealth of obsolete v4-only client software your customers use that might, if you're lucky, dribble away over the next few decades.
