Buy a product as a gift

Hi,

Sometime a customer what to buy a product as a present for another customer (existing or new).

We need a way for a customer (as well as an admin from the admin site) to be able to purchase a product - and get the invoices etc - and after that the product will be added to another customer.

only the customer who bought the product will see the invoice, order etc - the gift receiver will only see the product (and maybe a note from the buyer).

Thanks!

Ram
