Is it possible to create a product page link where the product price is shown in another currency?

For example, where the default currency is EUR, and we want to send a link to the product in USD can we generate a link along the lines of:

index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=1&currency=USD

Control the action over the button "Continue Shopping". Want to continue where you left off, not back to category listings? Leave you on the same product you have inserted in cart.

The TOS of VirtueMart and AGREED of Joomla is atm almost the same.
