I will take this as Oskar isn't really familiar with the details of
Dijjer (I think he is much more interested in the mathematics rather
than the practicalities of implementation). Dijjer does not scale its
routing tables with the log of the network size, basically it tries to
make the routing tables as big as possible within a given constraint
(I think the default is 20 connections). While this means that it
doesn't have log(N) scalability, in practice it doesn't really make
much difference and it means that we don't need to try to calculate
the total network size.

That is a good point. If you would like to add something to Dijjer's
FAQ about it, please feel free (its a wiki, I would do it myself but
i'm on the road).
