Wow. Thank you all for your comments. I don't have any demarcation points on the house for either Shaw or Telus - both just run in through the wall. What I have decided to do is run cat5e (either one run or maybe two) to two different spots on the house and leave access panels in the ceiling so I can get at them later and drill out from the wall if I need to punch them out later. I'm also going to have to extend the ground wire to the second location. Right now the services both come in to the old power mast but there is a new one as it had to get moved when I upgraded to 100 AMP service so I will run near both masts, in case the old one gets removed when I reside the house.
It is all a major pain but it is what it is. I don't think I can do anything else right now seeing as I am going to reside soon and there is no demarcation point to run to.
