Gemalto published an interesting e-government proof of concept site called Utopia Government, based on Coesys eGov 2.0 technology. I’m not endorsing Coesys in any way, I just saw it recently on Polish Interoperability Test for Electronic Signature. The technology uses smartcards and requires special plugin installed in user’s operating system.
