oh, sure.  Its for a real in-depth paper after the article is done, NGRouting is
implemented, released etc.  Most importantly, it won't require toad$$time :)

The difference in performance of fitting vs. linear will probably be variable
itself amongst various topologies and time of deployment; some of the other
suggestions like adding new reference points could prove to be just as good
while using less cpu.

When measuring performance exclusively, yes; but I would like to see some
empiric data before assuming all nodes will exhibit the same type of behavior
over time with regard to initial integration.  There has to be a parameter that
can be used to measure the success of the estimator in a useful way without
compromising anonymity, so that this parameter can be reported either in-freenet
like load or submitted at the will of the user to a central off-freenet
location.  Any ideas of such parameter?
