@shegy,
I am not one of the s2Member devs, but I very much doubt that any such extension is planned. Nor will most other membership plugins be producing such an extension.
Why not? Well, the key is in your phrase "there's no verification". Actually, it's impossible to verify that the IP address is accurate. There are all sorts of ways for users to be registered with an IP address for the "wrong" country -- and most of these reasons are perfectly legitimate.
One thing I should point out, though, is that if Stripe (and, I believe, PayPal too) is configured to demand a billing address, it has to match the registered address for the credit card being used. So that's already verifiable.
Nevertheless, the best anyone will be able to do is to (a) collect the data, and (b) charge the appropriate amounts based on the data you have. You might find this site helpful, though you won't be able to use PayPal if you want to use it: just Stripe.
