Enterprise MediaWiki hackathon

This page holds planning information for a possible "enterprise MediaWiki hackathon", as first discussed at SMWCon Fall 2013 in Berlin. The basic idea is that it will be a way for people (industry, academia and hackers) to work on "enterprise MediaWiki", i.e. non-Wikimedia Foundation, projects - which in practice probably means creating new extensions, modifying new extensions, working on skins, templates, forms and the like, and potentially working on documentation as well.

If you're interested in participating in such an event, feel free to add your opinions below, and add the " ~ " signature.

Dates and duration
''Ideas about the timing of this event - can be a year, season, month, or a specific set of dates. Should it be done before, after or alongside an existing event? Also, should it be held on a weekend or during the week? And how long should it last?''

Location
''Where should it be held? This could be a continent, country, city, or venue. Extra points if you're willing to nominate a location that could host the event for free.''

Focus
''The word "hackathon" comprises a variety of different formats. Should the focus be on teaching/outreach, on coming up with cool new ideas (possibly via judges and prizes), on getting existing local software polished and released, or on something else?''

Other stuff
''Miscellaneous thoughts. Is there a better word than "hackathon" for this event? Can we get sponsors? (The need for sponsors probably depends in large part on (a) whether the venue is free, and (b) whether there are prizes.) Should the whole thing be done as a Google Hangout?''
