I think it's a good idea. Just have a thumbnail of textures etc, an image of meshes, or a very short clip of sounds/music etc. on the database site, which can link to the owner's website for download. Except of course for those who wish there material to be hosted on the database site.
I believe this will help advertise the products, and be much easier for developers to locate the material available.
