In the august edition of linux format magazine they mention Intellibuild (iBuild), which supposedly makes creating custom Live Cd's easier (http://ibuild.livecd.net/). There are screenshots and Howtos available with it. Accesses software from Debian. Personally I haven't a clue if it works cos I haven't got that far yet and I am not sure how you would go about adding a non Debian appllication (I need something similar to MS Project and can't find anything on Debian although I found GanttPV, Planner and Gantt Project, which appear to have similar GUI interfaces as MS Project, but do not appear to be in Debian).
