Idea for a 'Cassette' Bee Hive

This is an idea for a new type of beehive made up of vertical units, each containing three combs of bees. It is a development of my 'Pagoda' hive (see video) using the smaller boxes stood on their ends, with comb guides arranged in threes on the underside of the top section.
Please bear in mind that this is just an idea, not a finished, developed hive, but if you want to play with it and develop it, please feel free. This is offered in the spirit of 'open source beekeeping'.
