Wow! Yup! Yummmm..!
 
Yep, I used cdfs to cp foo /mnt/cd/wd, fixed the cd, and cat /dev/sdD0/data gave me the file! (I thought that cdfs is bound somehow to 9660... so i tried to use scuzz.) 
Thanks to all who responded. Now i'm going to try the same with DVD disc. Hopefully, the 2GB limit is gone...
