Access the product ID from ShoppingCartValidateDomain hook?

[Skeets]

Is it impossible to access the product ID from the `ShoppingCartValidateDomain` hook?

From what I read, that seems to be the case... That would mean that it's impossible to validate the domain differently based on what product is being ordered... right?

I'm already validating the domain in the `ShoppingCartValidateCheckout` hook as well, and that works fine as I can access the `pid` in the session variable each item in the cart. But, I'd like to run the validation at an earlier step if at all possible, and prevent them from even adding the item to their cart.
