I'd say there are good arguments for both approaches, but Michael's 
approach is more elastic.

Let's say you install Firefox, and as the uninstall string give:

Firefox\uninstall.exe -I -made -a -typo


There, with server-side approach, you can always correct it.
With client-side approach, it's not that easy.

If you're still confused, and you're not sure which versions you have 
installed and which uninstall options you should use, I'd try something 

%ProgramFiles%\Mozilla\Firefox\uninstall.exe -ms (with timeout="30")
taskkill /f /im uninstall.exe
%ProgramFiles%\Mozilla\Firefox\uninstall.exe -msa (again, with 
timeout="30" in XML)
taskkill /f /im uninstall.exe

To tell some more, some time in the past, WPKG used a "server-side 
uninstallation instructions", but it was a bit buggy, and was removed - 
anyone wants to review old versions and extract the right code? :)
