This seems really promising, is it possible for this to play nice with a wikifarm?

If yes, what would be installation steps to only require a single copy of all user avatars?

You can install one single copy of the extension of meta wiki.

Could you clarify regarding what you mean by "meta"? Do you mean the config used by meta wiki...

I am hoping that users only need to upload an avatar once so that its displayed across all wikis connected by shared tables or centralauth instead of needing to have a copy of the avatar at each wiki.
