Well, one could attempt to add disclaimers as to all of the so called "practical limits", but, this would not only require the services of an expensive lawyer, but also, the resulting language would be way too long for a "signature line" on this forum software!
I think a politically correct, safe, non-offensive signature would be:
"The use of Home Automation is Limited...
Mostly by your imagination, budget, soon-to-be ex-spouse, time, creativity, knowledge of electronics, programming ability, and access to a suitable work space."
I think that would be closer to the truth... Maybe I will add that to my signature....
