[Hackathon] When is Hac5 going to be held?

Dear Haskell Hackathon folks, Does anybody know yet when exactly the fifth Hackathon (in Utrecht?) will be held? I would like for the upcoming darcs hacking sprint to part of this if possible :-) and would like to be able to give darcs hackers advance notice so that they can plan travel. Many thanks! -- Eric Kow http://www.nltg.brighton.ac.uk/home/Eric.Kow PGP Key ID: 08AC04F9
