First, actually, from what I understand, this doesn’t work quite the same way as hushmail does.
Second, according to their website they cannot compromise your mail because they don’t have the encryption keys. Also, being based in Switzerland (where they have strong privacy laws) means there isn’t really many appropriate documents that can be served.
Still, this isn’t open source, so I’m personally more interested in http://mailpile.is
