there are some interesting options to have tiles generated without  
caching using meta-data in the map file to control which layers are  
cached and which are not (allowing you to have base layers that are  
cached and a gps layer that isn't).

You can find details in the wiki:



In addition, you will likely want to do some custom coding to refresh  
the layer periodically.
