Analogy I used in letter to friends and family.

"The analogy is the electric grid.  Would you think it fair if General Electric had to pay our local electric company because their light bulbs were being used in the homes of the electric company's customers?  Wouldn't that make light bulbs very expensive?  Aren't the electric company's customers already paying for the electricity?  Shouldn't the PUD care less about what we use our electricity for?  Wouldn't that limit development of the light bulb market by making it hard for a new company to get started?"

I hope someone finds this useful.
