I considered powershell delivery, but there are a couple potential wrinkles with target coverage; the majority of vulnerable instances that will be encountered will likely be found on Windows Server 2003 boxes, as the patch publication occurred on May 14, 2008. 

Basically, by the time powershell became an integrated component in Windows Server O/S versions, Altiris had already released a fixed version of the Deployment Solution software; my gut tells me that finding vulnerable instances of Altiris where the powershell is present would be due to the optional installation of powershell, or the unlikely installation of old software. I think there will be greater coverage with the CmdStagerTFTP as tftp.exe will be present on the vast majority of targets.
