Oh, actually re the OP: for me, Vodafone's DSLite works pretty well, it appears to result in fairly "punchable" NAT that cooperates with ED and other games quite well without manual trickery, and the v6 implementation in the 2.3 beta is coming along nicely after some initial issues.
If you really, really, can't live with DSlite, You can contact their customer service and ask to have your connection set back to medieval IPv4 only, they will usually do that without any further hassle. They do not offer full-blown dual-stack though, since they are not sitting on a truckload of v4 address space. The only issues I've had so far were several times when Vodafone screwed up their provisioning, breaking v4 entirely for some hours.
