The Information Card Foundation is using Helios for its board election. Perfect use case: 50 people who will likely never all meet in person, but who need to vote on some issues. Helios provides them with a feature they literally could not achieve otherwise today: a secret ballot combined with real end-user verifiability that all votes were correctly captured and counted.
All of this practical interest is bringing up a few interesting needs, like a small widget you can post to your page that provides the status of the election and eventually the results. Fun things to think about.
