(thread about interwiki bots at toolserver)
Coincidentally, yesterday I released a MediaWiki extension which, if accepted on Wikimedia projects, may make interwiki bots much less busy. See http://meta.wikimedia.org/wiki/A_newer_look_at_the_interwiki_link
It also works by manual writing of the interwikis. I don't think it's the good way. *You're not taking into account page moves. What will you do when a page is moved? (by a low tech user which knows nothing about the global wiki) *The articles will still have a 'preferred' title at the interwiki wiki. That means discussing about article titles, "Move to English name", "No, that's not", "Interwikis with pages on Chinese are ugly!"...
IMHO it should be a shared table referencing the wiki and page ids. Then you provide a Special page showing all pages on that group. You'd reference it as 'include this page into the group XX:sometitle is on'. You can also provide some space for free-form commenting (such as explaining the difference with another page). Obviously, all of that must be properly logged, which with SUL should be much easier.
