Thufir, I have no experience with dar, but I came across this one:
  dirsplit --no-act -s 700M ~/temp/

I set the size as 1M just to see what it would do {--no-act}. I did 
notice that the largest file in the folder must be smaller than the 
split size, which was OK for me, but may not be for you. This would 
still be kind of a manual process, ie using k3b to make each cd from the 
splitup folders.

Perhaps backuppc would achieve your goals (I can't remember it's process).
