When will they come up with an easy/cheap "out of the box" solution for small/medium business so they can plug their dsl & cable modem and have some redundant connection?

Yes i know there are workarounds with NAT66. Wasn't that one of the selling points of ipv6 - not to have to use NAT ?

goto www.pfsense.org Pfsense is all you need for this and every other firewall / router / captive portal / ... project and it's opensource with optional paid support if required

Well it shouldn't be hard for the isp's to set up ipv6-to-ipv4 tunnels, thus they can give out ipv6 address' to their customers
while still allowing them to access ipv4 based systems. But that would cost money and isp's only want to make money

I personally experimented with it in one of the schools i work; you can get an ipv6 subnet for free to experiment with at one of the
many tunnel brokers. The problem is that currently I have to use my ipv4 address on my router/firewall to tunnel to an ipv6 broker
in another country (kind of slow) .... then i have a zillion ipv6 address i can assign to each of my computers(yey no more NAT)

Now only to find something to do with my fancy ipv6 adress, cuss that animated gif at kame.net get boring after a while
