can these two systems co-exist?

Yes, IPv6 supports 6to4 tunneling, allowing ipv6 traffic to travel over segments of the network otherwise only accessible via ipv4.

Hell many of the Linux distros, and a few other pieces of software now offer both ipv4, and ipv6 specific download sites, etc. IPv6 also has google's blessing, for their own internal ulterior motives.

Considering all OS's currently available (and sadly, I include XP in that), all PC's, and all core and edge routers support IPv6, the only cost issue is the damn cheapo routers many people are using in their home. Which hell, even about 10-20% of those (yay D-Link) support IPv6 as well.

Virtually all operating systems support IPv6. It's the networking CPE that will need replacing.
That said, I checked my print servers and cameras.
The Axis cameras may be able to get a new NIC for IPv6 but not the rest of the equipment.

I'm not sure how a dual stack architecture will work. Only high end routers currently offer it. I looked at a Linksys WRT610N, but the specs still say it is an N draft 2.0 version and nothing about dual stack compatibility for the router side. The manual does show how to set up DHCP for IPv6 on the private side.

I think it would be great to set up a private IPv6 and IPv4 network (dual stack) lab just to see how well it works.
