Matt 26z - i have the answers to a couple of these.

3. Considering the new responsibilities secondary producers have in record keeping, what can happen to them if a sponsor/provider (primary producer) falsified the documents given to them, and unbeknownst to the secondary producer, underage models were shot?
they're fucked. check your i.d.s carefully to be sure that they look like the model in question, and if a model looks 14, probably best not to use him unless you really trust the content provider in question,

4. Are the common types of foreign photo ID's valid forms of 2257 age ID?
no. in the new regs, it specifies that only passports are valid i.d. for non u.s. models.


5. Must 2257 and URL info be kept for models appearing only in banner ad's?
if they are sexually explicit, yes.

i recommend that you read 2257 and the new regs. as one attorney i spoke with said, a lot of it is very straightforward. some is pretty vague, but parts pertaining to some of your questions are very specific.
