Technicalities
The Proxy Server feature is a reverse proxy using Apache mod_proxy.
Basically mod_proxy forwards requests that Apache receives on to another running process through a specific port. For example, if you wanted to set up Rails with Mongrel, you could have the Mongrel server running in the background and just have mod_proxy send incoming requests through Mongrel (or Tomcat, or some other daemon).
You can only forward requests to localhost, and only on ports above 8000.
Daemon Processes
A daemon process is a server process that listens for communication from remote clients. For example, the Apache Web server is a daemon that listens for TCP socket connections from Web browser client applications. Some servers, such as TeamSpeak or game servers, might also listen for UDP packets.
A DreamHost PS (or Dedicated Server) account permits you to run daemon server processes. They will be limited to the server resources (CPU/RAM) you pay for. This differs from a shared hosting plan, where these processes could adversely affect other users on the same server.
Daemon processes that bind to a port (on which they listen for incoming connections) will be visible from the Internet. DreamHost does not employ any sort of firewall or port blocking on their network.
