Power-Plug Mania

February and march 2008 - 4 FOSS events in 4 different countries in Europe - eager to present a OLPC in all of them, i finally get one OLPC with a US Standard power plug.
No Problem to find a adapter to the German System, my adapter looks exactly like that.
But only one Event "Chemnitzer Linuxtage" is in Germany.
For the Fosdem in Brussels i need a hole in the power plug ;-) .
The OpenExpo in Bern seems to need the Swiss System with a third Pole. And a view hours before McGiwer (Pawel) invited me to FOD2008 in Poland, power plug there no idea ;)
For a World Traveler maybe it is normal to change power plugs all the time, but all that countries are my neighbors - !
