There is one dirty solution. The technique that cellular geolocation uses. Place several Wireless Access Points (APs) around with a maximum separation of 200m. Then for the clients, its a simple case of finding the nearest AP. That AP's position will be roughly the client's position. (OK! I just made that up!)
And as for non wifi users, radio location can be completely ruled out. The only option left is to find the network node closest to the user. This network node will most probably be the ISP's gateway server. Then identify the gateway server's location using some database (hmmm.. that sounds eerily like IP geolocation!). The only problem is that the Gateway may service a huge geographic area- so precise positioning is not possible. Devices closer to users- like network switches and DSLAMs could have provided more precise positioning. But they are mostly dumb devices and do not expose their identity (technically, they work on datalink protocols, but we need IP layer info). So even that is not possible. Anybody has other theories? I am especially interested in hearing about any wireless radio location techniques.
