What percentage of your equipment already supports IPv6?  Most 5 year old
pieces of equipement already have IPv6 support.  It just needs to be enabled.

IPv6 is *not* a "forklift upgrade".  It's a parallel deployment that can
be done incrementally one service at a time.  The first step is to get
the bits to you.

Turning on IPv6 doesn't really affect the amount of bandwith you use.

You don't need your ISP to support IPv6 to turn on IPv6.  You just need
a IPv4 path to someone who does support IPv6.

Most IPv4 only ISPs are already carrying IPv6 traffic.  It's just
encapsulated by one of the early deployment methods.

Turn on IPv6 should be a $0 cost.  Fully supporting IPv6 on all the services
you offer will have some cost.
