Bookmarked - will definitely try that. I wonder if an ink-jet will work 
just as well...

I estimated 7e9 bits of data (probably an underestimate due to error 
correction bits etc) and an area of 17 square inches. sqrt(7e9/17) is 
about 20000 dpi.

Maybe, but you'd probably still have to hack the hardware significantly 
to allow the lightscribe functionality to work on the data side of the 
disc at a much higher resolution.
