I'm applying for the iPhone developer program, and it mentioned they may need business documents, possibly including a seller's permit. I have all of the other documents in order, but I was looking on CalGOLD and it says "All businesses selling or leasing tangible property must obtain a Seller's Permit."
Does software count as tangible property if it is only distributed online?
