I ought to point out that Poser models are copyrighted, and it would be a breach of that copyright for anybody to send you actual meshes 'in the clear' - whether you have Poser yourself or not. This restriction will also apply to clothing and textures etc., depending on what their terms of use are. The Poser figures could be encoded with Objaction Mover so that you could open them only if you have Poser - the rest of the package would depend on selecting items which allow redistribution.
