Unlike most others encyclopedias, Wikipedia is about ease of editing too, and editing is made harder by the abiguity in the convert-links-once solution. What I like in the idea of aliases is the total control of the author over what he links to. This won't be possible if Wiki software is the thing that decides about the conversion.
I would say that it is exactly the other way around. Tim's proposal is not ambiguous and does not require any searching for terms in name spaces. Your's, however, does.
