  find /mnt/cdrom -type f -exec dd if={} of=/dev/null \;

I've heard of people runing md5sum's on /dev/cdrom, but I've never got
it to work since the md5sum seems to change from the disk image to the
device file after it's burned.  (the once or twice I tried it)

Or maybe that was back when I was using the "-pad" on cdrecord?  
Maybe I should try it again sometime!   :-)

It's nothing new.  I've been doing it for a LONG time.

Don't know.  I'm using Redhat's stock kernels and
I've never tried mounting more than 5 or 6 at once.

Yup.  On the mount command (with no fstab entry), you don't even 
need to specify the filesystem type of "auto".
