I was gonna add detail to the wiki page, but didn't see a way to do that. To be more precise, we're talking about the ability to run a service (daemon) in a self-containd fashion such as what you are forced to do when you've bought a basic "shell account" from an ISP. Sometimes you won't get much of a runtime environment, and even fewer permissions. Sometimes you'll even be in a jail shell where your "/" isn't the real system root, and you do not even have read access to files outside of your jailed filesystem.
But note this won't work on typical webhosting account. These will usually not allow any inbound ports aside from 21,22,25,80,110,443. Unless they are incompetent or mentally challenged anyway. :) So do people still buy shell accounts much? -- Psi webmaster (http://psi-im.org) im:[EMAIL PROTECTED] http://halr9000.com
