Uh, whut? I expect my ssh sessions to survive a 4G->3G handover, and
if they happen to go over IPv6, I want them to survive.
If your SSH sessions could survive a change in address assignment (which
often happens in a handover), they could survive a change in address
family assignment as well.
Unfortunately, TCP - upon which ssh is built - uses the routing
identifiers as the host identifiers, and so this doesn't work.
The important reason to upgrade is to get higher speeds, not to get
access to new L3 tech.
I lose my YouTube streams when I get handed over from 3G to 2G, too,
for example. I can live with that. I much prefer it to YouTube not
working 3G as well, even though that might very well be considered a
more "consistent" user experience.
I don't agree with you at all. I don't believe I would lose the stream
when doing that handoff in our network, it might buffer some more
(because EDGE is slower than HSDPA), but you wouldn't lose the stream.
But the stream would almost certainly be coming to a newly assigned IP
address (and once you're doing that, who cares if the family changes too?)
Consistent behaviour (apart from speed) on all networks is really
important for me, and I'd imagine it is for most users as well.
The *only* inconsistency would be when you're accessing the IPv6-only
part of the Internet, of which there's currently none that consumers
care about.
