I suggest rather WIHU or XPlode. WIHU has simple to use conditionals so after a little fiddling,you could specify specifically to allow a computer to install a certain software. WIHU also looks more like a part of Windows Setup, rather then manually going through and customizing the appearance of XPlode or WPI. WIHU can also change Computer Name and other little things if you so desire. WIHU uses a INI system, which when first looking at it, might seem daunting, but it's really simple. XPlode's new ver4 has a selection screen, where the appearance is governed by an HTML file, and the actual apps are all stored in an XML file, which can be easily checked for errors in a Web Browswer or the like. the XML is also rather simple, and the included PDF contains excellent documentation to get you started with all it's little funcitons.
