I know of a bunch of equipment - much of it no longer supported - with 
IPv4 *ONLY* networking. Quite a few network-enabled printers for example.
Lots of CURRENTLY MADE equipment - for example, the solar MPPT devices I 
use here - don't support IPv6 in any form, and are not likely to.
Lots of PLCs. I know of many PVR/DVR devices without V6 support. Webcams. 
CBus network interfaces (they may have now, but all the ones I've ever 
seen don't, and replacing them is far from an "inexpensive upgrade").

I guess THAT will depend on what IPv6-only content there is.
I can't imagine any of the "mainstream" sites dropping IPv4 any time soon, 
because they don't want to lose the existing IPv4-only users. Catch-22.

Haven't been looking <implied> in earnest or specifically for </implied>

And yes, absence of evidence is certainly not evidence of absence!

"IPv6 support" isn't what I was asking though.
I was asking for a "stepping-stone" for users who may have a significant 
(to them) outlay in their "home computer network" or "small office 
network" - perhaps network storage, media-centre, security systems, 
possibly even VoIP devices - that may not all support IPv6.

Those in multi-billion-dollar companies who just chalk up a few percent of 
revenue to upgrading, or who make a "multi-million-dollar commitment" to 
upgrading are all well and good, but as network operators and/or ISPs, 
we're "middle-men". The people at the other end of the string - those at 
home and in small offices particularly (because they're the ones for whom 
even modest additional expense will hurt most) also need to be considered 
in this whole "upgrade process".

Yes, IPv6 support, but no indication if it is capable of doing a V6/V4 
"translation" for legacy devices. I know a change to IPv6 should be a 
complete change, but some people simply won't be ABLE TO. Or, will have to 
sacrafice a bunch of capabilities in order to. Yes, I'm sure a modern 
computer is quite capable of running an IPv6 stack AND an IPv4 stack 
simultaneously, and to access local devices on the network via whichever 
protocol is required... but (lets just play devils advocate here for a 
minute)...

Take the case of my neighbour. Had major problems with breakins, installed 
a 20-camera security system with a fancy digital video recorder and 
internet access. He got a unit. Chinese. No support, company since 
changed to making whatever. Cost him more than he can afford to replace. 
It's only IPv4. Sure, he can access it from his computer on his local 
network, but when he needs it most is when he's away. Right now, he can 
connect to his home internet connection and see what's going on. His 
recorder can call out (email) to notify him of an alarm, and send a 
picture. It needs internet access periodically to set the time etc.
How's this scenario work with the above modem (or any of the others you've 
generously listed)?
He's a builder, not a network guru. All these "IP address" settings he had 
to fill in to get it to work required assistance, but at least he got it 
going. I'm not even sure it's POSSIBLE with an "IPv6 router" with IPv4 
devices on the LAN side, is it? (Please tell me it "just works, and the 
router does the same NAT function, except the outside address is IPv6!")

You may be right. But there will still be a non-trivial number who won't.
