Any way to have an app transcend Spaces?

[danembraceddc]

I know that I can set an app to use any of the Spaces but is there a way to have an app stay above or transcend Spaces, E.G. have Twitteriffic or Pownce stay in the same spot above other apps as I move between Spaces?

in the spaces prefs you can set apps to be active in all spaces. don't know that this will keep them 'on top' but they'll be active in all of 'em at least. i do this with ichat/adium
