Honest question, what makes setting up a Tor Delay so prohibitive? What would be the possibility of say buying a few rasberry pi's and then placing them in discreet locations where wi-fi is free and piggy backing on their network? e.g. Every McDonald's restaurant

It's not hard to set up a Tor relay. However, to run a good relay, you need a stable internet connection with at least 20KByte/s of symmetric bandwidth. I think that you also need ports to be forwarded (manually, or with uPnP/PMP) in order to run a relay. It's not likely that you'll get stability or port forwarding by piggy-backing on some business' wifi. What's more, I suspect that the Tor community would frown upon this sort of activity.
