After going through this, it seems as though only one show per performer would have to be recorded, dted and kept for 7 years:

Thirty-two commenters commented that the requirement that a copy of
each depiction be maintained would be unduly burdensome, leading to
vast stocks of magazines and videotapes, and even storage of computer
images would be unmanageable and prohibitive for small businesses.
Thirty-five commenters also commented that the requirement to keep
copies of each image is impossible to comply with due to the vast
amount of data involved in storing digital images, especially, e.g.,
producers of live streaming video. The Department declines to adopt
these comments. Maintaining one copy of each publication, production,
or depiction is critical to making the inspection process meaningful.
Commercial publishers and producers can reasonably be expected to
comply. Furthermore, modern computer and disk storage capacities make
digital archiving and back-up relatively inexpensive and space-
efficient. Finally, reviewing identification records in a vacuum would
be meaningless without being able to cross-reference the depictions,
and having the depictions on hand is necessary to determine whether in
fact age-verification files are being maintained for each performer in
a given depiction. In addition, without the depictions, inspectors
could not confirm that each book, magazine, periodical, film, videotape
or other matter has affixed to it a statement describing the location
of the records, as required by the existing regulations. Exceptions
cannot be made for producers of digital depictions, and indeed, it is
likely less onerous to store digital images than paper images. Children
are just as easily exploited in live streaming video as in any other
visual medium. Therefore, an exception cannot be made for producers of
live streaming video.

Can someone tell me if I am wrong? I have two civil rights attorneys calling me back today, as well as an entertainment attorney. Hopefully they will help shed some light on this.
