You could try stunnel. Although it also wraps the connection in ssl. http://www.stunnel.org
I'm actually just playing with it after reading about it on Darren's blog. Great functionality and seems to be quite fault tolerant. It also has an option for transparent mode to preserve the originating IP. (Having problems getting transparent mode going on Sol10 though...) Anyhow, mildly off-topic so I'll keep it at that.. corey.
