First off, thank you for all the work you have done making wikipedia available offline. Offline is greatly needed for archive and for internet poor countries. I am involved with a grant proposal for an extension for easy offline xml generation for a wiki. We won't be using the zim format due to the easy of having xml used within a mobile app. Our goal is to create an extension for use with any mediawiki installation so that offline comparable mobile apps or any application that can parse xml can read the wiki offline. I would appreciate if you could comment and even support this endeavor as we bring offline support to all the mediawiki installations in an easy to use extension and mobile app for iOS and android.
