Important note for getting pages' interwikis in a batch: http://de.wikipedia.org/w/api.php?action=parse&text=%5C%7B%5C%7B:Test%5C...
Either the bot could figure out what interwikis belong together then, or
maybe a marker could placed in between: http://de.wikipedia.org/w/api.php?action=parse&text=%5C%7B%5C%7B:Test%5C...
[[MediaWiki:Iwmarker]] (or 'Llmarker'?) would have to be set up by the MediaWiki developers with [[en:/de:Abuse-save-mark]] as content (but this is potentially misusable).
