Hi guys, Seems to be a new development in this area: CryptoCP by Daniel Bernstein, see the relevant portions at 41''30 and 59''45 of his recent talk http://27c3.iphoneblog.de/recordings/4295.html (don't know how to watch the video from there though, I downloaded the talk this morning from another site but the link is down right now).
While he didn't discuss much CryptoCP per se, if I had to make a _guess_ from what he said it would be a mix of TCP in userspace with authenticated encryption provided by his software NaCl http://nacl.cace-project.eu/box.html . NaCl actually implements cryptographic primitives mainly based on his own crypto primitives such as Salsa family and Poly1305 but he has also hinted what could be some sort of equivalent with "standard" primitives (see previous link, bottom of the page). So a common use case, on the client side applications would proxify their network requests through CryptoCP which would encrypt them, simulate TCP and send UDP packets to the destination server. Notice that in this case it would be quite similar to what libjingle is currently implementing: OpenSSL can be used to SSL_write and SSL_read to/from a userspace TCP stream.
