It's kind of a simple concept once you figure it out, although I'm not 
really familiar with any pre-existing packages specifically for GIS type 
of work.  There are a few people that have packages to do heat maps for 
click locations on web pages, you could probably adapt that pretty 
easily -- especially if you were doing, say, MapServer/PHP mapscript. 
For example, http://www.labsmedia.com/clickheat/index.html has PHP 
source to do it for web pages, but the heat map generating is in its own 
class and can be used separately.
