yep, exactly.

here's an example url: (rejoin if your reader chops this up)

http://pitapb.cs.colorado.edu/cgi-bin/bouldermapserv46? 
version=1.0.0&SERVICE=WFS&request=GetFeature&TYPENAME=buildings&outputfo 
rmat=KML&bbox=-105.2578135375255,39.99054716346154,-105.24581541255,40.0 
0435364626606

you can create a network link in GE pointing at this url.

not yet, although that sounds like the way to do it.

my reading of the KML spec has been more demand driven--"how do i  
produce this". i need to take a more careful look at it along with  
your most helpful comments to see how to proceed. i haven't done a  
lot with templates, so i'll have to look at that too.

thanks for the feedback.

later,
