This is exactly the plan. The /56 is parceled into /64s for
each invididual vserver gust.
There's a problem, however. My hoster won't (can't) give me
more than a /56 for each rack. I need at least two /56
however (one IPv4 /32 for each IPv6 /64).
It just occured to me that I can set up a local 6to4 relay
router http://wiki.debian.org/DebianIPv6 and produce private
IPv6 space for each public IPv4 /32.
Are there problems associated with this, or can I go ahead
with it?

I don't understand that remark yet, as I'm pretty new to IPv6 and
networking in general.
