Update 2: From what I can remember of IPN. It does not matter that much that it comes back "INVALID" because all that is saying is that you did not return the data back the way PayPal wanted. But the transaction still will go through and you should still receive the transaction info from the first IPN response.

I've temporarily moved on, but will be coming back to this...was a bit tired of tearning at my hair. Will report back here - but this is a really good point...I could probably live with an unvalidated for the time being as we're not talking about huge amount of sales attracting thousands of cheats
