Amos -
The Athenian Assembly consisted of all 50,000 freeborn male adult Athenians.
The Assembly had approval and veto powers over every piece of city-state legislation.

Democracy today is necesarily many steps removed from that kind of immediacy, and the reason is the logistics required in dealing with huge populations.
I didn't understand your suggested solution, but I have often wondered why, with the I.T. we have available today, our democracy isn't a lot more immediate than it is.
