Camino Downloads

Despite the many allures of the more popular Firefox, I continue to use Camino, the made–for–Mac Gecko Firefox alternative.
When Camino downloads something, it creates the file that will be downloaded, and a file of the same name with ".part" appended to the file name. When the download is complete the ".part" file goes away.
I'd like to make a system for Hazel to avoid downloaded files until they are complete. I'm thinking of some combination of Hazel and applescript to tag a download if a file of its same name with a ".part" exists. How to untag them is fuzzier.
To make matters worse, I'm a Tiger user and will continue to be so for a while, so I can't rely on Leopard metadata.
I'd love to hear what you all think. Thanks!
