IPv6 Transit?

Hi, Does anyone have any info on IPv6 deployment at the Tier-1 / Tier-1.5 level? We are multi-homed to both Level3 and Abovenet in the UK and Level3 only in the US. Level3 did have a promising sounding beta program last year but that seems to have stalled. Abovenet apparently have no schedule to deploy v6 at the moment. I would like to be able to v6 enable our network but without a transit provider that’s going to prove a bit tricky. Any thoughts appreciated! Cheers, Mat Sharpe Qube Networks Ltd P.S. I hope I’m not about to re-start the who is/is not a Tier-1 / Tier-2 argument! :)
