This looks like an interesting conference. It is partly organized by Peter Shane, who edited a very good collection of essays on e-democracy, published by Routledge last year.

In the same vein, but on the other side of the Atlantic, there's a conference at De Montfort University, organized by Lawrence Pratchett and Scott Wright. No website yet, but it's on Wednesday November 23rd.

Hopefully the papers will be available online in due course.
