I'm with Acadia: if the product vendor has been smart and/or kind enough to include links to the necessary software to decode the mesh, I don't have a problem with it at all. The biggest failing I see with products, encoded and non-encoded, is sparse documentation that assumes a depth of knowledge on the buyer's part, or that the buyer has all of the necessary utilities to prepare the product for use. Clear documentation will overcome most objections I might have to a product, and that includes accurate links (and correct e-mails for the vendors, in case we need to contact them for support).
