Has anybody had any luck in setting this up? I don't know how to tell screen to launch different ros nodes in different screen-windows of the same screen-session. I can do it manually, but i would ideally like to make it part of my boot script.

I think you can use "screen -X screen -U" in the launch-prefix attribute. -X option sends a command to a running screen.

But I don't know how to set the "default" launch-prefix, you may need to edit all the node tags like below:

  < node pkg="your_pkg" type="your_prog" name="foo"
     launch-prefix="screen -X screen -U"/>

does "screen -U roslaunch ..." resolve your problem?

when you run "screen -U" in a screen-window, screen will make another screen-window in your screen-session and run the command you specified.

it would be good to make an alias to "screen -U roslaunch" like below:

 $ alias slaunch="screen -U roslaunch"
 $ slaunch your_awesome_program.launch

What I want is to launch different nodes in different screen windows. What you suggested will just lunch all the nodes specified in the launch file in one screen window.
