I was just wondering if there was a way to automagically move things around, symlink, and/or read the RH rpm database to 'direct' apt-get, so that a system could be moved from RH to a Debian-like system that could use apt-get - keeping the same versions of the software installed, and still able to use software compiled/installed outside of either package management system. Once moved, I would anticipate dropping rpm and use apt, so keeping the two sync'ed wouldn't be an obstacle.

Just an idle thought...
