[aprssig] track.cgi and google maps

I've been working on getting Google Maps working in the track cgi.  
Unfortunately, it is not going well. It seems GMap does not do well  
when the number of icons rises, so something like the normal  
breadcrumb cgi is very slow (30 seconds to open a page with less than  
400 points) on Safari, and refuses to plot all icons on Firefox:

Using lines instead of breadcrumbs is faster, but has a problem. In  
this set of data, there are a couple outlying points that mess up the  
data, and this is not uncommon. In my own drawing routines, I am able  
to detect this, and do not draw outlying points.

call=n4rve&start=240&line=1&gmap=13

http://www.findu.com/cgi-bin/track.cgi? 
call=n4rve&start=240&degree=19&line=1

I'd like some private email reports of what happens with the first  
cgi above in IE, maybe that will help me decide what should be the  
default mode for the track cgi...
