Multi currency per product

Hi,
I have a problem I hope to be able to explain.

My customer has to sell different products, arriving from different countries. He would sell these products starting by the sale price of the products, in order not to loose money on the exchange rate.

For example: a product coming from Switzerland should be defined with a sale price of 200 CHF, and not start from the euros conversion of 200 CHF (that could change depending on the daily currency change).

Hope to have clarified my problem.

On the other hand, should be possible to define a default currency on backend, and another one by code on frontend?

Regards
