I've done some more fiddling and come up with:

#!/bin/awk -f
BEGIN {
        LIMIT=680000

        CDCOUNT=1
        SIZE=0
        PATHS=""
}
{
        if (SIZE + $1 > LIMIT) {
                SIZE = 0
                print "mkisofs -JraT -o CDROM" CDCOUNT ".iso " PATHS
                PATHS = ""
                CDCOUNT++
        }
        SIZE += $1
        PATHS = PATHS " " $2
}
## End of awk

This will print out the mkisofs command to create each ISO. It's up to you
to then run each one manually or end up doing:

        du -sk * | sort -k2 | mklist.awk > createisos.sh
        sh createisos.sh

if you do this, make sure you've got enough disk space :-)

Caution! Untested. It shouldn't break anything but use at own risk :)

You could even end up adding:

        print "cdrecord -v dev=..."

type line just after the print "mkisofs" line to have output that you can
plonk in a script and just run to burn the CDs... or change "print" to a
call to system, so instead of outputing the lines, it executes them there
and then...
