I was hoping to do it in one step with my own IPv6 PI space and do the
allocation and routing on the servers/routers/firewalls, see how that
goes and when the time was right, just announce my prefix to the world :)

Thanks for the URL, I was not aware of it. I guess I'll have to
experiment with prefixes from that and see hot it goes.

I'll probably do that also.
