You need this /64 prefix for the server (not for the client) which then
assigns IP-addresses to ISATAP clients within this prefix. So in a way,
if Dan has access to an ISATAP-server, this would solve his problem.
It's probably not as easy a solution as 6to4 but I wanted to point out
this option. But it's incorrect that Dan himself needs his own /64
prefix. A provider or other entity that runs the ISATAP-server needs a
prefix.

See above: the primary function of ISATAP is to connect one client, not
a whole net. Basically: ISATAP integrates single clients into a site
that has a certain prefix and advertises this prefix to connected
clients.
Cheers,
