For example, if you were distributing a JAR or, say, a setup ZIP file containing an installer, then you could always just build the JAR or ZIP file on the fly with that user's custom configuration, and return that to the user. Of course, you wouldn't want to be generating a ZIP file upon every request if this were a high-traffic system. -chris
