The realtor is not the front line, they don't sell anything they don't get paid for, and they would be the last people I would want trying to sell technology no matter what the standard or how easy it is supposed to be. I am working on a "system" to get the architects in my area to start getting the clients interested in talking to me about what tech. they can have in their homes, then they can add to their sale because they will add my spec to their designs. Now I have the client nice and early in the project instead of just before the drywall goes up.
Most builders I have dealt with over the last 12 years either still don't get it, but at least ask the client if they want something, or they think all this stuff is neat, but are not interested in learning any more than just the basics about it because they feel they need to know something, not everything, thats why I am here.
I mentioned before a standard is a good idea and might very well work for the tract home industry, things have to be done quickly and efficiently, plus you could make a standard that would cover 90% of those jobs because they all have the same level of equipment and type of systems.
