|Subject:||Where Am I? Protocol|
|It seems to me that this problem can be partly addressed with a simple "where am I" protocol that works on the same principle as DHCP. No centralized infrastructure required. Just look for a WhereAmI service in the same way you look for a DHCP server, then ask it for some information. It would reply back with a set of elements that might include lat/long/altitude coordinates, perhaps along with some unstructured or semi-structured data (tags would be especially handy). Not perfect, but it should work well enough, and it can be deployed pretty quickly.|
