-    The website's monetary field/widget can become website-aware, and thus
-    should be able to use a pricelist somehow available through the session?
-    Why not directly the qweb context. There's also a method stored in
-    the ecommerce controller in website_sale, would that one be a good/better
-    idea? => just eval some string and hope that's a pricelist?
-
-    Either way, it also gets the ability to fetch the "company" pricelist
-    via website.get_current().company_id (or 'res_company' in the qweb context)
-
-    The widget then needs to call (ir.currency).compute(from_currency,
-    to_currency, value) to convert the company's to the user's during display
-    and the other way around during parsing
