Thanks Steve. I am clear about the mapping part. I am not so sure about
streaming/uploading near-real-time GPS data from on-site to webserver
across WPA?
I can not speak to WPA, I'm not sure I know that protocol, but if have a
cell phone that that can do HTTP GET requests to a server, you can
trivially write a php page the gets the url and writes the fields to a
database and have mapserver display that. So that is pretty real-time.
So you phone would ping a url like
http://yourserver.com/track.php?lat=<lat>&lon=<lon>&device=<uid>&...
And then write a track.php to fetch the paramaters and stuff them into
the DB.

Bill,
There are probably many solutions available depending on the various
technical components that you might have in the solution. One possible
solution might be something along these lines:
1) stream data to some service that you probably have to build
2) have said service load the points into a postgres/postgis database
3) create a mapfile with a LAYER to disply the data from postgis
4) Use a client like OpenLayers to render you map from mapserver
5) add a timer event to refresh your map every X secs
