presumably the appeal is to the sweatshop type of big SI who would like all their slaves colocated so they can get a few more hours graft in at night, maybe under a 'panopticon' design modelled on the old workhouses so the inmates, whoops, young professionals, could be kept under surveillance for signs of not-joining-in? As big projects don't stay in the same location for ever, these 'work houses' could be built in modular fashion , maybe using trusted Portakabin technology, so that they could be moved and reassembled as required...
