That is probably because you appear to have failed to read the top half of that post. An external ssh session will break during renumbering, no matter what nat capability might exist, so the only thing worth discussing is an internal one. Deploying a ULA prefix alongside whatever external one might exist will allow the internal ssh to persist forever while the external prefix is changed on a minute by minute basis. > Yet many of my ssh sessions are > active for days or weeks quite happily and their existance represents > my > mid term memory about what I'm working on.

No argument about the impact, but you have not demonstrated a need for 66nat beyond wanting it so that nothing changes except the size of the address. This will not be true on a number of fronts, so perpetuating an architectural impediment in a futile attempt to avoid reality is not a reasonable argument. Vendors will build what you say you want to buy, so don't box yourself in by insisting on perpetuating the past without trying to move beyond it first...
