Well I'm not such a Linux programmer, so I'm sorry if it sounds crazy...

It's not crazy. It's just that... even if you COULD get a docking connector for a CD-ROM drive working, it would still require programming to do all of the things you want to do (ripping the CD for example). So if you aren't a programmer, you would be going to a lot of effort to build something that didn't do anything.

There are two other non-empeg products on the market that will do ripping right in your dash. They are expensive and they do not have as much storage as the empeg, but they exist.
