At least it's better than the Diebold debacle in the states.
-Estonia has an internet voting system
-Estonia just released the source code to their voting system
Even if internet voting is a terrible idea, a transparent election system is a very good idea, and releasing the source code for your voting system is a big step in that direction.
I think it's a bad idea as well, but like you, I think it's weird to be upset that there are people who want to help achieve the best solution/compromise, in the event that your country's government vote to implement something like this.
I'm as pro-government as the next European, but we can all think of horrible government project failures.
