I think I actually remember seeing something in a simlar vein — a combination laundromat / coffee shop / Internet cafe, specifically — somewhere in Santa Cruz when I went back to visit a couple of years ago.
Seems like a great idea, to me at least! Also, instead of having one of those ridiculous vending machines, if there’s a cafe with a register built in, you could just sell people measured portions out of a huge vat of 7th Generation or some other eco-friendly detergant.
