Yes, you're absolutely right in all the above. The lesson to take from 
this, is that any secure
e-voting scheme, whether based on cryptography or not, must solve the 
problem *end to end*,
ie. from the point where the voters cast their votes, all the way to 
where the votes are counted.
What they are describing here is one particular component of a system, 
but not the system
in its entirety. In other words, this technology may well keep the votes 
secret while being
transmitted along the communications link, but it can't guarantee to 
keep them secret, before
and after transmission.

Also, whenever you see the word "unbreakable", it's time to get very
