How do you remove/disable Evolution Data Server process

From the looks of it, Evolution Data Server is a required component for Gnome and should not be used.

The Evolution Data Server provides a single database for common, desktop-wide information, such as a user's address book or calendar events. It is also a dependency of the clock applet from the gnome-applets package, 2.10 release.

So in short, removing Evolution Data Server would either remove alot of other programs, or completely bork your install.

From the Ubuntu Forums:

It's also not a big memory loss; the little volume applet on the panel takes far more real ram than evolution-data-server.
