Ich habe wyrd (http://freshmeat.net/projects/wyrd/) noch in meiner todo-Liste stehen. Aber ich habe mir das Ding noch nicht näher angesehen. Klingt aber gut:

Wyrd is a curses front-end for Remind, a powerful calendar and alarm application. The display features a scrollable time table suitable for visualizing your schedule at a glance. Wyrd integrates with an external editor of your choice to make editing of reminder files more efficient, and provides hotkeys to quickly access the most common Remind options. Other features include extensive configurability, Mutt-like interface design, and minimal resource requirements.
