Customize menu bar?

[pulsewidth947]

Is it possible to customise the menu bar at the top of the screen?

By this i mean move the icons next to the clock. I can command+drag the apple ones, but that doesnt work for my others (pspware, iscrobbler, synergy)

Depends on the app. Most are in a specific applications preferences.
