I just found out about hacker spaces. For a nice example of a hack space, see The Metalab. Such places seem quite suitable for work on individual public projects and for growing teams by sorting out the wheat from the chaff.
It's a pity there are no hacker spaces east of Vienna. I wonder if one could be set up in Vilnius. There probably are enough people around. but quite a bit of organising work (see Hackerspace Design Patterns [PDF]) needs to be done to establish a hacker space. I would do it, but I am overbooked as it is. Any takers?
