I've often thought that this would be a good idea, for several reasons.
Since nobody seems to really be SURE what the lifetime of the discs is, 
and since we've heard about the potential ink bleed-through, it would 
be nice to know if your extensive collection of CD's is slowly
self-destructing.  If it was possible to monitor the error rate
(especially correctable errors), disks could be copied using a writeable
optical drive, BEFORE its too late.
