Actually, it isn't particularly hard at all... Turn on privacy addressing
on each of the hosts (if it isn't on by default) and then put a linux
firewall in front of them with a relatively simple ip6tables configuration
for outbound only.

(The linux firewall could be as simple as a WRT-54G running
dd-wrt or such).
