There is a presentation about it here.
The pres includes a high-level risk analysis, which acknowledges various
things like the possibility for fraud. An interesting point
they make is that you would have to trust the "central system" which
I presume aggregates the votes. They say this is equivalent to
trusting the "Election Committee" for existing paper based elections,
and therefore that's ok.
But I wonder if the underlying assumption is really true.
If existing paper ballot election counts are
conducted in public, then I don't see how it could be true.
