Feeling kinda silly, but this has been bugging me for a few days now. I
can't use cdparanoia (or ripperx) unless I'm root, but as far as I can
tell, all the group permissions should allow me to.
Transcript below shows that I'm in group cdrom, but cdparanoia fails to
find the cdrom unless I'm root. I even logged back out and into X in
the Windows-esqu off-chance that it would help. Shoulda had more faith
:-)
What am I doing wrong?

Found an accessible SCSI CDROM drive.
Looking at revision of the SG interface in use...
SG interface version 3.1.25; OK.
CDROM model sensed sensed: MITSUMI CR-48XCTE 1.0B
Checking for SCSI emulation...
Drive is ATAPI (using SCSI host adaptor emulation)
Checking for MMC style command set...
Drive is MMC style
DMA scatter/gather table entries: 256
table entry size: 32768 bytes
maximum theoretical transfer: 3566 sectors
Setting default read size to 13 sectors (30576 bytes).
Verifying CDDA command set...
Expected command set reads OK.
