That paper was very interesting. I think it might in fact contain the
answer for writing smart selectivity estimators for geometrical data, now
someone only needs to be brave enough to try to code it. Btw., it also
contains a number interesting references regarding R-trees and selectivity
estimation in general.
Whodda thunk there's genuine information to be found on the Web ... :)
