The NSA is, yes. Hopefully this will be alleviated by some of the new bills
that are in congress now. Either way, the government can't control it forever,
only until mass-marketed cryptography software starts being produced outside
the US.

If a certificate isn't signed by a certifying authority, then all of the people
who receive messages signed with that certificate will have to have the
certificate in their own personal "keyring" or similar file. This decreases
security because not only does it make the certificates harder to use, it puts
the burden of key verification on the sender instead of the certifying
authority.

I doubt it. Have you looked at the current list of viruses that the
commercial scanners can detect and remove? It is in the 5-digit range, and an
average file can be scanned in less than a second. With the microprocessor
world moving like it is, I doubt that the above statement will be true anytime
soon.
My opinion is that most IS shops, right now, want a way to scan incoming emails
for viruses. I know my company does. If this need is not filled by free
software, it will be (and is already being) filled by commercial software.

The concept sounds nice. However the expected release date was the middle of
last year, and the author hasn't even modified some of the pages on that site
since last april. So when can we really expect to see something like this?
