I looked at all the mentioned and they look like they provide coworking center system for offices(daily free seats, reservations and to on). My idea was more simple - something like directory with "I am rails developer and looking for place to work next 3 months in Prague" or "we have 2 seats in office, for $XY a month". Thanks for ideas, I will have to think about it more.
