First, why? What problem does this actually solve, other than the technical daring-do of it all? This can all be done easily with paper (see my post about Minnesota's process).
Second, it violates the principle of a secret ballot. Repudiation would require voters to reveal who they voted for, to match ballot to (digital) signature. So it's not viable as a mechanism for a global recount.
