[ale] launching apps to specific desktops?

[jloden at toughguy.net (Jay Loden)]

I (finally) helped my best friend get off Windows and onto Linux.  He's big 
into having stuff launch at startup on his machine, and I've never done this 
on Linux.  We sorted out how to use the ~/.kde/Autostart folder to launch a 
script that does what he wants, except for one detail.  He would like to 
launch app "foo" onto Desktop 1 and app "bar" onto Desktop 2, for example. 

Does anyone know how (if) this can be accomplished from a script?  Is this 
something that can be set, like DISPLAY ? 

It's a Mandrake 10 system, if that makes any difference (you never know).
