Hi - 2 separate things I guess. One can still pay with a credit card directly without requiring a PayPal account (we call it guest payment) but in most cases it depends on how the merchant has configured his payment options. But that said there are a few corner cases where we cannot allow direct credit card payments (eg. Preapprovals in Adaptive Payments) due to credit card policies.
Regarding accepting payments from countries that are outside of PayPal networks, it really comes down to what is allowed by the local govt authorities around cross border transactions.
