Nothing of the sort. The isatap client is within the administrative 
domain of
the isatap router. The isatap router serves a /64 dhcpv6 prefix 
delegation to the
client. The client uses this prefix to connect as many additional hosts 
as it wishes
using, e.g., the multi-link subnet model and RA proxies. It's just like 
what happens
when the GGSN serves a /64 to a mobile via the IPv6 PDP context; it has 
nothing
at all to do with multiple administrative boundaries. Again, the main 
point is
that the isatap client can connect many hosts - not just one.
