But this is in different part of the world etc., I don't think one extra bitcoin hackathon will do any harm :)
I was facetiously referring to the Tom Williams and MyBitcoin.com fiasco. Anyways, good luck with your event. Sounds like it'll be a lot of fun and the Aalto Garage is an awesome place! If i was still in Finland, I'd be there!
Finland is a good place to do it, now that many former Nokia engineers are out of jobs.
Finland is also home to a high percentage of the best hackers in the world, especially during the peak of the demoscene (Future Crew, etc.) days.
