I'm another person who'd like to see a version of OZ that comes without the pim functionality.
I'm a sysadmin and I find myself needing to check my systems for security issues now and then so Off the top of my head my dream image may include:
Konquerer, Calculator, QPE-Gaim, Wellenreiter, Nessus (Not in the feeds, Once the openembedded site comes back up maybe I'll try my hand at getting it compiled), nmap, fbvnc and vncviewer, kismet,zsafe, and tcpdump.
Maybe a option would be to offer a 'base' opie package that does include anything other than konsose installed as a application and then use cardfs images like cordump made to install bundles of packages for different tasks.
Since I dont have a way to Sync the Zaurus with my Mac the pims end up just a waste of space for me.
