accept adds austin buttons choice complications country crafting currencies currency deal deny down drop files global hosting inexplicably info input lot minimum multiple offer paypal price product prompted sales selling similar spike strong sweet tough traffic units

Trying to understand how e-Junkie and PayPal deal with multiple currencies. I know in PayPal I can choose to accept, deny, or be prompted about other currencies. But I haven't found similar info on e-Junkie yet. I have noticed my first big traffic spike was from another country, and I want to be able to offer sales global for my product.
Is there any way to do this without crafting new buttons for each currency? I'm sure it adds a lot of complications, but a drop down currency choice would be sweet.
Input?

Would be nice, although I don't know if that would affect hosting your own files, which inexplicably has a minimum price of 0.99 'currency units'. Tough luck if you're selling in a strong currency...
