On the bright side, they finally admit to having plans to enable it - and for the time being, they have very good private peering with Hurricane Electric, making a tunnel work pretty well as a stopgap. In this area, the only decent ISP available is Vivaciti (using the old Bulldog/C&W LLU kit) - good, but not a patch on Virgin for speed.
I've just moved all my email over to Fastmail (who are dual-stack with the exception of the SMTP handling) with Nuevasync to handle the iOS clients, over IPv6 when connectivity allows. (Were there one, an IPv6-only user could now email me.)
Pity the poor ADSL customers still using BT resellers - for a long time, BT refused to fix the firmware bug in their core routers which caused some IPv6 packets to get corrupted in transit. The official line was that IPv6 is not supported over their ADSL links!
Yep, I saw that. I’d imagine that IPv6 would be a major benefit for software that does lots of NAT traversal, like online games.
I moved to Andrews & Arnold for my ADSL last week, partially motivated by the desire to get native IPv6 before this launch day, but mostly because I was fed up with juddering video streaming at peak times on BE. It has improved matters significantly.
The streaming problem on Be is apparently down to iPlayer! (The extra traffic via Akamai was enough to choke up Be's Akamai link; they're working on upgrading it, but for some reason it's taking a long time.)
NAT traversal is really only an issue when both ends are NATted; most games would be communicating with a central server, which avoids that problem entirely. Pure peer to peer setups like Skype and BitTorrent will benefit, although with most routers supporting UPnP these days that's a fairly minor problem - any peer to peer application can open a listening socket for the outside world quite easily anyway.
Behind an elderly (pre-UPnP) router or a jackbooted firewall it's a problem (Dundee University blocks inbound connections, not because of NAT but plain old firewall rules) but neither of those will be changed by IPv6 any time soon anyway.

One of their senior people has been testing out their IPv6 connectivity by playing WOW over it today:
