SecureDVD could come in handy..

Downside being it's a DVD so if what your working on doesn't have a DVD Drive...
Upside is it's MULTIPLE Live CD's, geared towards security, forensics and system rescue on a Single Disc
If nothing else the List of Distribution s that is on it could come in handy for you
I'm sure you already have the link for the Live CD List site, but I'll post it here for anyone else that may be reading this thread..
