From www.publications.parliament.uk comes great news about the dangers of electronic (on-line) voting being kept away from democracy for a while longer:
Mrs. Laing: To ask the Secretary of State for Justice whether there are any plans to introduce e-voting mechanisms before the local and European elections in 2009. 
Mr. Wills: No. The Government do not plan to introduce e-voting for the 2009 European or local elections.
The way forward more generally on e-voting will be informed by the valuable experience gained from earlier pilots, analysis of the responses to the election day consultation, and further development work including the possible further testing of e-voting solutions in non-statutory elections.
Mrs. Laing: To ask the Secretary of State for Justice whether there are any plans for further e-voting pilots in the next 12 months. 
Mr. Wills: The Government have no plans for further e-voting pilots in statutory elections at this stage.
