Nonetheless, many CDR packs carry a warning in the fine print that 
says NOT to use alcohol-based inks for writing on the things.

I mentioned several brands of "CDR Pens" previously, but one I didn't 
mention (because I've forgotten the name, and it's not here %-) 
actually claimed to be "water based".  I had real doubts about how 
well it would work as such inks tend not to stick on hard shiney 
surfaces.  But it seems to be okay, if you're not *too* impatient.  It 
was available in Fine in a four-colour pack (from OfficeWorks in Oz 
IIRC).

I'd really like to know if there is any formulation difference between 
the Staedtler LUMOCOLOR OHP series and their "CD-R PEN", or whether 
this new model for CDRs is just a marketing ploy.  It's of some 
practical interest, because the OHP pens are commonly available in 
three size ranges (Superfine, Fine, and Medium) and in six-colour 
packs as well as individual colours; whereas the "CD-R PEN" is only in 
Medium/Black around here, and not readily available anyway.

Cheers, Phred.
