Bill,
Am still not particularly proficient with MapServer to help with the "how" --
instead, I'm curious about the "how near" real time. Within 10 seconds or 10
minutes?
Also, how much data? if it is just x,y,z info could you have the machine
that's reading the GPS append points to a (say) ShapeFile, and send the whole
thing? This would work if your ShapeFile held the last couple of hundred
points; Then it might be possible to display those points + another layer that
would have an accumulation of the points, and a process on the server that
would append the newest points to the accumulated file.
I'll confess to being more than a little curious about what you are doing...
Ken

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?
Cheers, Bill

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
