tell me Mark,
when will you turn off -all- IPv4 in your network?
no snmp/aaa, no syslog, no radius, no licensed s/w keyed to a v4 address,
no need to keep logs for leos' (whats the data retention law in your jurisdiction?)
etc...
simple switching of datagrams over non-v4 transport is trivial. th O&M behnd
running production is a slightly longer path and the legal requirements these
days didn't exisit a decade ago. Chris was optimistic at 10+ years.
imho
