Yes. Otherwise your exchange would be listed by Zen as well.

Zen have an IPv6 FAQ, which says IPv6 is being worked on but will not be announced until it is ready to launch as a fully-supported element of their products.

Though it's second best, you can use an IPv6 tunnel. Zen have direct IPv4 peering with Goscomb in London, who host the SixXS gblon2 gateway. For me, the penalty of IPv6 via this route is 7ms extra round trip latency and the 20 bytes per packet overhead of protocol 41.
