You don't have to delay supporting IPv6 just because 99% of your
routers have no support. There are things like GRE tunnels,
MPLS with 6PE and MPLS with 6VPE which can be used to carry IPv6
packets over v4. And there are various gateway services like 
Teredo, 6to4, NAT-PT and the new v6 NAT which is not quite baked yet,
all of which allow some degree of interworking. Obviously an
ISP needs some devices to support IPv6 in order to make this
work, but not all devices.

That's why I suggest that all smaller ISPs should go to ARIN's
v6 wiki <http://www.getipv6.info/index.php/Main_Page>, get educated 
about v6, and figure out a plan of action.

There is more than one way to skin this cat.
