IMHO, material transparency is the only difficult to meet requirement. Paper works fine to wrap most cold cuts and it's already used extensively in packaging for fruits and vegetables.

People are already willing to pay premium for organic and other hard to inspect/certify labels; it doesn't seem outside the realm of possibility that people would be ok buying paper-wrapped prosciutto that has some similar stamp of quality.

Paper also works fine if you're ordering your prosciutto at the deli counter.

But even waxed paper isn't going to prevent the prosciutto from drying out for more than a day or two. The whole point of the plastic that prosciutto is often sold in is to keep it good for months, since it's usually a low-volume item that may sit on the shelf for a couple weeks or more.

Personally I find paper wrapped items from the local deli fine, but I'd be pretty skeptical of any food products shipped only in paper -- too easy to contaminate.
