Over the last couple of weeks, I've taken a few steps to remove some of the WMF-specific bits of the MobileFrontend code base: https://bugzilla.wikimedia.org/show_bug.cgi?id=34144 https://bugzilla.wikimedia.org/show_bug.cgi?id=34145
Also, now if you view an article with "useformat=mobile" in the URL's query string, MobileFrontend will keep the mobile view enabled as you browse page to page until you explicitly exit the mobile view.
While MobileFrontend has now been generalized enough to be used beyond the WMF cluster, there are still quit a few things that could be done to improve the ease of out-of-the-box usage. For instance, adding configurable WURFL support (which I believe should be fairly straightforward - this is out of date but the same idea should still work: http://lists.wikimedia.org/pipermail/wikitech-l/2012-January/057478.html) or making it possible to use path-based modifiers to signify mobile view (eg http://mywiki.com/wiki/Article -> http://mywiki.com/wiki/m/Article - https://bugzilla.wikimedia.org/show_bug.cgi?id=35178).
It would be great if anyone can help test/provide feedback for the changes that have been made, and especially if anyone wants to help add the features mentioned above!
