I would be interested in a UK Hackathon, and there are a fair number of
heavy-duty UK techies, I suppose the way forward would be a weekend
event, and the crux would be, primarily, suitable premises.
* Good wifi, plenty of mains outlets.
* Food and drink
* Presentation facilities
* Cheap accommodation
* Reasonably easy to get to (this is always a problem in the UK of course)
Perhaps the best way is to start small but scalable?
