Here's message I posted on the last last summer describing how to do  
this for OS X. I suspect each platform will have its own procedure.

  To hide an application process in OS X, open the Info.plist file in  
the Contents folder of the application package. Add this to the <dict>  
section (it doesn't seem to matter where):

<key>NSBGOnly</key>
<string>1</string>

  Doing this will remove the process from the Dock, and from any menus  
that list active (visible) processes. To show it again, you can either  
put in a 0 instead of a 1 for the <key>, or you can remove the whole  
thing.

I tried it and it didn't work, then I noticed in the mail list archive  
that this apparently was broken in Panther. I searched Apple Developer  
web site and discovered that the name of the key has been changed to  
LSUIElement.

So insert the following to create a faceless application (one that  
doesn't appear in Force Quit list or in Dock):

<key> LSUIElement </key>
<string>1</string>

It's best to use the Property List Editor application to do this rather  
than a text editor.
