I agree with JMAV, I too have done 100's of theaters, multi room systems etc etc... every home and owners requirements are different, different levels of quality, different combinations of equipment and on and on.

I do know that there are alot of newer products out there that certainly can help make it easier to wire a house, runnning component or HD over cat 5, even audio distrubution over cat 5 can save on the wire costs, but the client has to spend a great deal more on the equipment end, so these solutions are not for the basic system installs.
The moment you allow people to terminate jacks with any colour code, you create confusion. Just look at the thread over at integration pros about wire colour codes, even speaker wire, right now is wired a few different ways based on who you talk to. (red/black/& white/green or red/green & white/black) Cedia has a code for this, not everyone follows it, even companies like Russound don't follow the cedia standard.
I also don't think that the architects and builders really give a hoot, all they want is the client to get whatever they want in the way of technology, and for us not to get in the way of the building of the house. They don't typically understand all that we do, they just know they need us to do it. They also are not interested in knowing any more than just the basics, after that it's up to us to figure out how to make everything work.

Part of what Wesley has said implied that his plan is to make it easier and cheaper for the builder or home owner to have things installed, and by having a standard, just about anyone can do the work, which is a big reason why so many posts here are negative.

In high tech homes it takes alot more than just wire to bring it all together, I can just imagine the call I could get from a frustrated home owner after "anybody" took on the job of doing their system now that it is so easy, "help me, when I turn the lights on in the laundry the speakers in the bathroom come on, and when someone rings the doorbell my internet connected fridge orders 2,000.00 worth of groceries."

Maybe for areas where they are building 1000 homes, a standard could be useful, but the custom side of this industry is just that "CUSTOM" we have to think on our feet and know what we are doing, this is why we get paid for what we do.
