So, I am currently using a Tunnelbroker (he.net) to provide IPv6 for the times I need it on my Edgerouter - this is slow (as in, I get high latency and quite slow speeds). I've looked for a solution and there really isn't. 6to4 is considered depreciated and SixXS isn't accepting any new registrations. This has practically forced me to disable IPv6 on my main network and move IPv6 to a secondary SSID on yet another VLAN.
IPv6 is now considered as a must-have in my opinion. I manage all my servers out on the internet with IPv6 and more and more sites are IPv6 ready.
We've talked about IPv6 with BigPipe in the past - it is one of those ongoing discussions but as most tunnelbrokers are encouraging their users to discuss IPv6 options with their ISP I'm now pushing this to BigPipe and really hope that some of the community would join me.
Edit: Whoops after a server migration (moving this server from home to Amazon AWS) I broke the sad kitten / puppy script. IPv6 is on the way however! Thanks guys for your support!
