in the ipv6-up script I:
   ip route add $PREFIX${PPP_REMOTE#fe80:} dev ${PPP_IFACE}
(which strips the link local address, and prepends it with my global prefix)

so that data meant for that machine goes down the correct ppp interface.

at the moment I only have a /64, so I can't carve up my allocated space even
if I wanted to :-(

I could just create a script to list all the interfaces that could ever be
used, and it'll pick up the ones that are active.
