The architecture of the Physical Web is about not requiring a central server for things to work. We want it to be distributed and federated, like the web. Nothing we do requires a single central server. As you currently describe it, your approach would likely involve such a server. We are experimenting with wifi through mDNS and wifi-direct (it's available in early form in our Physical Web app for Android) With these, we embed the URL into the wifi router itself, using it much like a bluetooth beacon. I think this is getting to the spirit of what you'd like to do. The only issue we're wrestling with is that this type of approach enables offline or unreachable beacons which raises some security concerns. We're looking into using a signed package format to fix that problem.
