Just came across a reference to this little gem of a conference right in our backyard:

“constitution making and direct democracy”
Saturday, July 31 through Wednesday, Aug. 4, 2010
From the brochure (PDF, 588KB):
Dear Fellow Global Citizen,
We invite you to what we expect to be a groundbreaking conference in the heart of a city known for earthquakes – political, cultural and geological.
Welcome to the 2010 Global Forum on Modern Direct Democracy, a five-day international event that includes the two-day U.S. Conference on Initiative and Referendum, a first-of-its kind national meeting.
Around the world, direct democracy provides an avenue for citizens to adopt new constitutions – or amend their old ones. At the same time, those constitutions govern direct democracy.
In 2010, Californians are expected to vote on ballot initiatives that would permit them to call a special convention to rewrite the constitution of the U.S.’s largest state. If approved by voters, it would be only the third such convention in California’s history – and the first since 1879. Among the parts of the constitution likely to see change: the rules that govern direct democracy.  In San Francisco, exactly a century after a local lawyer was elected governor and quickly convinced Californians to adopt the most robust direct democracy in the Americas, we meet to answer two questions. What are the best ways to use direct democracy for the making and remaking of constitutions? And what systems and structures of direct democracy belong in those constitutions?
In San Francisco, where the Golden Gate Bridge marks the intersection of the continent and the ocean, academics, journalists and political leaders will gather to discuss another intersection: that between constitutions and direct democracy. The 2010 Global Forum on Modern Direct Democracy — the third global forum after Aarau/Switzerland 2008 and Seoul/South Korea 2009 — seeks to reflect on the factors that have limited the growth of direct democracy in North America (and indeed, in so many places around the world) to states, provinces and local governments. What paths exist to build direct democracy into federal constitutions around the globe? For an introduction and overview on the Global Forum process please download our new book “Global Citizens in Charge” at iri-europe.org.
Among other things, the program includes a public event/dinner on digital direct democracy (August 2).
The conference is organized by Initiative and Referendum Institute Europe, Korea Democracy Foundation, Center for Governmental Studies, and New America Foundation.
