One can use timeout="seconds" option in the install command (see 
http://wpkg.org/index.php/Firefox for examples).

For example, timeout="10", means that after 10 seconds WPKG will assume 
that command execution has ended (which will also need an exit code, 
probably "-1", or a patch (not yet implemented) from bugzilla to accept 
any access code).
WPKG will not kill the process, even if it's still running.


So, logically, it should be fairly easy to update WSH through WPKG:

1) write a batch script that will wait a couple of seconds, and then 
will update WSH - WSH-update.bat:


ping 127.0.0.1 -n 30>NUL
update_WSH /silent


2) write an XML that will start this WSH-update, with a small timeout:

  <install timeout="5" cmd='\\server\updates\WPKG-update.bat' >
   <exit code="-1" />
   <exit code="0" />
  </install>


3) start it as a last command (priority="0")



WPKG will end before WSH update is even started (as we ping for 30 
seconds, and then update WSH).

I didn't test it personally, but it should work that way.
