Many thanks for the responses so far. So if I can get the account login/pass then any dealer could assist with equipment modifications, etc. As far as equipment, I was looking at replacing the router with an ASUS AC66 as I have that in my current home and change the AVR to a Pioneer SC 67 that I currently use and update the projector to an Epson 5020. Would those pose problems for the old dealer as they are different from what is currently in the home? Is one brand of product more challenging to work with than another? Or will the lack of familiarity of a brand of product deter the current dealer from wanting to be involved?
