STunnel and Ubuntu Lucid Packaging

I'm to understand that in order to use HAProxy with SSL, you need to put something like STunnel in front of HAProxy to decrypt the SSL stream. I suppose you could also use nginx, STunnel is more flexible and could decrypt other protocols besides HTTP.

The current version of STunnel requires a patch to include the X- Forwarded-For header when the request is an HTTPS request.

I'm developing an application stack for Node.js and I want to support WebSockets. I'm developing for Ubuntu and it would be preferable to use the stunnel4 package in Ubuntu, but it seems that a patch is required to add the X-Forwarded-For header to make full use of HAProxy.

Questions:

• Is the STunnel in Ubuntu Lucid ready to go? (Maverick?) Can it be made to work?
• If not, has someone repackaged stunnel4 with the X-Forwarded-For patch applied?
• Is there an alternative to STunnel that would support WebSockets?
