I still don't see the problem. If you dual license Wikitravel, your authors will have no direct disadvantage whatsoever. It's just another sentence on the article submission form. Both licenses grant derivative rights.

I see a problem; none of the current Wikimedia projects wants to be a travel guide, so where o where will Wikitravel's text be used? The last thing I want is travel guide type text such as "Good places to eat in Mexico City" in our Wikipedia article on Mexico City. That type of stuff is not appropriate for an encyclopedia. Just provide an external link to the Wikitravel article at [[Mexico City]].

We plan on coercing both the CC and GNU people to make their copyleft content licenses copy/paste compatible anyway, so I don't see any real benefits for Wikitravel to be dual licensed now; all that would accomplish is confuse their contributors (part of the whole point of the CC/Att-SA license is to be /less/ confusing than other copyleft content licenses - such as the FDL).
