Cool idea, except for the non-unifrom distribution of IPs and the number
of users behind each IP. Furthermore, this distribution does indeed vary
from site to site, so analysis tools would have to generalize the distribution
(which is most likely a member of the gama family) and then paramtertize this
for each site to achieve a robust random sampling methodology - tricky stuff.
I liked you first idea more.
Jim.
