I don't think it would work for physically settled commodity futures because contract specifications require a particular quality of product, and that's part of the motivation to trade via an exchange.

But it would work for securities that have no distinguishable attributes from one another, especially if the extant problem with trading those securities is market access.

It doesn't work. But, I clearly remember this being something IBM advertised extensively.
