In 1812, Elbridge Gerry, governor of Massachusettes, signed a bill that re-districted his state to the benefit of the Democratic Republican Party. This fiddling with boundaries for political benefit has since been called gerrymandering as the new shape of the territory was said to look like a salamander. More on this here.
An interesting question is "Will Interactive Democracy foster more gerrymandering?"
Well, it's upto the local people to decide if demarcation lines should be redrawn. But, in the ID system, each person is empowered to vote issue by issue, so there may be less desire for manipulation for party benefit. And if one party were to try, the opposition can drum up support to oppose it.
