To anyone interested in the legal side of things, this might be an interesting read:
http://myndflame.com/blogs/myndflame-the-blog/blizzard-machinima-law-part-2/
It is a commentary on Blizzard's fair use policy towards machinima. For those who don't know it, WoW machinima are cinematics made from ingame footage or 3d scenes set up using Blizzard's assets. The tl;dr summary of the article: if it is noncommercial, you can use any of their assets and music. It is reasonable that this would extend to Warcraft III.
For more backup, Blizzard featured a map,
Molten Core, on their custom map vault (which is pre-2006, iirc).
Obviously, we won't get a point-blank "You are allowed to use WoW models in Warcraft 3". Blizzard's general rule towards modding was something along the line of "we do not support the editor, make sure you follow da rulez".

As for server space, I'm pretty sure Ralle has a server on the level of terabytes.

But anyway, it seems that this thread has devolved away from the question at hand. The posts should pertain to the question at hand: have a section or not? Even if it is implemented, it doesn't necessarily mean that it will follow genin's specifications. It would be up to the staff ultimately.
I'm confused. Did this thread/poll suddenly become defining?
Nope. It won't determine anything--that is up to the staff. This should just be considered a discussion. If the majority were in favor, it wouldn't hurt the chances of it being implemented, but it wouldn't guarantee it being implemented.

One thing that is interesting: when Pharaoh made a similar topic, there wasn't an uproar of hostility. From the start of this thread, I've felt like personal bias has played a big role in this poll and its discussion, and that is a bit disappointing (I suppose it is a fact of life though).
