Your employer is in a situation to fix that.

How can a NPT based solution know that "ISP A" is a walled garden?

How will a NPT based solution create proper router redundancy?  Terminating
both ISPs on the same router is not what I'd call "redundant connections".

> c) homenet did not try to resolve ND problems of proper withdrawal for stale prefixes. If uplink to one carrier would be lost - it does not discuss how it would be informed to the hosts on the first hop.

This has been addressed independent of Homenet, because it affects
ISP flash renumbering as well.

If phrased that way, neither do "solution 1" or "solution 2" today.
