I actually can't see a technical difference.
Most intranets work by:
1) intentionally limiting a customer's access to the global Internet
2) playing DNS tricks
3) HTTP proxy tricks
4) having a local name space.
I think that walled-gardens are the political NAT44 of IPv6.
We can, if we want, stick our head in the sand like we did for NAT44,
letting the marketplace produce create an arms race between network
operators and application creators. Or, we can do like we finally did
with BEHAVE and specify something.
I'm here in homenet because I care about e2e, I want to avoid NAT66, and
I see great utility in having globably unique addresses everywhere, even
if they are not globally routable/accessible.
(ps: I shipped NAT44 products in 1994. I hate myself for helping kill
e2e. I shipped it with split-horizon DNS standard. It was all stupid. )
