VVPATs do not add complexity, they cheaply allow a layman to verify if a proper record of his/her vote was produced.

I can't parse your last sentence, sorry.

PS: Yes, I would prefer to redesign the whole thing from scratch and tightly integrate physical and electronic records, as in an optical scanner, but this is very unlikely to happen anytime soon.

Fortunately that's not what I am arguing. I am pushing for VVPATs instead. :)

Yes, in Brazil we don't even have the possibility of recounts, so reassuring! :)

The state-of-the-art is the STAR Voting system, which will probably not be manufactured due to lack of interest from industry partners:

Optical scanners have a very good cost-benefit in terms of accuracy, complexity, transparency and usability.

If you refer to paperless electronic voting, it will be always vulnerable to malicious insiders. In order to possibly prevent that, you would have to lock it down in such a way that no one would be able to audit the result after the fact, undermining the sole purpose of a public election.

I can't reproduce your issues, but perhaps resolving the DOI works better: http://doi.org/10.13140/RG.2.2.16240.97287
