The best implementation for sharing a file in a challenge would be something like "Use this model in a scene about..." where the model might be related, unrelated, or completely unidentifiable.. And of course, the download should be absolutely no more than 1 meg for us slow dial-up connections.. and preferably smaller than 500k.. I've done some fairly complex models that could be zipped under 500k, so it's not that much of a restriction. What do you think? =) Rosh
