Simple rule with posting models that I go by:
If it's not yours, regardless of whether it is free/open source, or not, then don't post it unless you specifically have permission from the owner.
Free and open source models doesn't mean you can do what you like with them, they are usually for personal use only unless they have a specific license that says otherwise, that means they cannot be distributed or sold without permission.
That's why the SWG EMU's and the various WOW EMU's don't supply you with a client, you have to own the original disks and download their launcher to be able to play on the EMU's, that way they're only supplying their own code to run assets you already own, but if they supplied the client or any part, including the models, textures, audio etc they would be distributing copyrighted material and breaking the law, and would be shut down by SOE (or whatever they call themselves now), or Blizzard etc.
That's actually the only reason SWGEMU has lasted as long as it has, because they're not actually distributing any copyrighted material, they're just providing code and a sever t use the material you have already paid to own the rights to use.
Edit: As far as i'm aware it's only the SWG server source code that has been released to open source, no the client nor the media that comes with the client, you still have to own the original disks to play on a server.
