Using *nix "last" command or similar - get workstation including remote desktop (VNC) logins

My situation: I set up an Ant build process on a suse server, and multiple developers have access to the server. There is only one user defined for the build process, so all the devs use that build user - things get a little messy when the automated emails come out to everyone but nobody knows who the build messages are for.
