I kinda explained that in my post, for the home/personal use ie. once off cable install by the home owner there is going to be fark all difference, used everyday or used for diagnoses of more complex LAN's etc well that's where units like the CIQ-100 come into play.
You are correct about running cables through the roof but like i said the standards only apply to licensed and qualified installers and/or energised cables directly or indirectly connected prior to the communications boundary.
You are also correct, if i was to build a house i would pay someone to do it as the cost is feathered out over the total but for someone that just wants to run a quick cable well i certainly wouldn't pay someone like me/you if they had a good idea of what to do.
