If some one puts a GPRS chip in a cell phone and even if it does not
work inside a 
building, i am sure the service provider can mentain a database of last
reported 
location, there MUST BE a point before u enter the building, and the
ambulance and 
police can always use that that information.

my 2 cents

-- like in a 
cellphone.  However, the problem is that GPS reception inside buildings
is not good, 
so it would not work reliably.

register their location in some fashion, or (in an enterprise setting)
involve ethernet switches noting the MAC address and port of the IP
phone and tying it to some form of network topology database.  The
latter approach strikes me as being extremely ugly, as it is not exactly
lightweight.
