Agreed with Jan. If you want to modify permanently the environment 
variables of Windows machines, one of the tools you
can use is VBS. I think you will find articles about which API calls to 
use to do this in VBS.
Ant can kick off a VBS script if you do
<exec executable="wscript.exe">
         <arg value="full path to vbs file"/>
</exec>

Regards,

Antoine
