"The Dutch government has released the source code of online voting software piloted during the recent European Parliament elections under an open source licence, according to reports(http://fastlink.headstar.com/oss2)."

"The technology, which enabled 5,000 Dutch citizens living abroad to vote online, was made public by Open Standards and Open Source Software (OSOSS – http://www.ososs.nl), a body that promotes open source software in government. The software was developed by LogicaCMG (http://www.logicacmg.com) in partnership with the Security of Systems group at the University of Nijmegen (http://www.cs.kun.nl/~bart/sos.html)"

Sounds like an excellent move.
