I'm not quite sure what this has to do with DreamHost web hosting. It's really more of a client-side thing and mostly has to do with tunneling through firewalls and such. I think the article I originally linked to covers it well and it's really just a matter of doing what the original author did.
Besides, the idea comes originally from Joe's blog. If you like the idea and benefit from it, I think you should link to his content rather than ripping it off and putting it in the DreamHost wiki.
