Beekeeping by Rotation System from Celle Germany

A little while back I put out some requests on the web for ideas on how to keep hive numbers steady for locations where there is a limited amount of space for reproduction and it was suggested to me that I look at the Dutch Aalster method, or the Rotation method from Celle, Germany.

What little english info I able to find on these approaches suggests it is really a method for disease/pest control that is designed to keep productive populations during flows while creating breaks in the brood cycle and cycling out old comb from the brood nest. Though many variations seem to exist, the most detailed information on the approach comes in the form of this IWF documentary.
