We sell expensive items, so we have 3 payment options:

- credit card (with address verification)
- paypal
- bank transfer

To avoid fraud, I want to arrange them so the payment option displayed is a function of risk - by relating them to tax classes (geo_zones):

- geo_zone 1 (uk) - ALL 3 types
- geo_zone 2 (euope & trusted countries) - Paypal & bank transfer
- geo_zone 3 (rest of world) - bank transfer only

i think that the decision would be implemented in checkout_process.php - when the payment options are displayed.... it would be a simple if, then else routine .. but im a PHP newbie, so cant fathom a solution .. 

Any ideas? Im sure others will want this too.. as online fraud / paypal fraud is so on the rise. 

cheers, :)
