While pulling this cable alongside power cable, it is possible (and if the holes are tight, likely) that some insulation will rub/scrape off both the power and and the data cable, thus livening the foil screen on the data cable to 230V. A person handling the data cable is then at risk of shock, possibly leading to burns or ventricular fibrillation - an often fatal condition. If your house has a crawl space underneath the floor (ie not poured concrete floor) then it would be trivial for someone like myself (I would charge for my time) to drill through the bottom plate of the the walls at each data socket location, cut out a flushbox hole in the gib, drop cat5e down the wall and through the hole in the bottom plate, fit easy-fix flushbox and data socket and voilá, job done. Requires overalls, drill and good sense of direction. Yuri
