To what end?  All the end-users will be subjected to using outdated software while everyone else moves forward with corrected and more advanced features.  Maybe a discounted, upgrade incentive might draw new users to download a free version but you already have DAZStudio and Blender readily available to the public.  Renderosity is not a content powerhouse that caters equally to Poser and DAZ, it sways to where the market is directed.  Free software needs to have solid content support; without it, trying to encourage current support may backfire from competition within.
