Not having done more than read the docs/faq/etc, I'm going to go on a limb and echo this.  

My motivation for using kadischi is the ability to create various custom live cds ala INSERT, Knoppix but based on the flavor of linux I know inside and out.  Although creating custom RPMs could theoretically get me there, I can see two problems with this approach

First... the subjective objection... Some tasks just feel wrong (to me) in a RPM ... such as modifying Desktop Patterns and menus.  

Second... a practical one... When I'm first trying something out, I'd like some simpler option.  Right now (if I read the docs write), I've got a number of post-RPM ways to modify the CD.  If people no longer have a way to make and test something before creating an entire RPM, it's going to real hurt the usefulness of this tool.  Right now, it feels like a progression of ways to make modifications that can be used as appropriate.  Granted I'm exagerating, but I've never liked having to build a factory before I can see if my sink idea is any good.

my (uninformed?) 2cents...
