[wpkg-users] creative ideas to spread out the running of wpkg installs? [SEC=UNCLASSIFIED]

[Michael Chinn]

Forogot to mention, one of the other benefits of divorcing the package 
from the installation that might suit your need is that you can use 
other methods to download the package beyond CIFS networking. wget or 
even some sort of a bittorent would suit some environments (eg 
Azureus.exe "http://example.com/test.torrent")
