Global bar to display global information

[Jérémy Compostella]

All,

As many user, I use Emacs as my full desktop environment on several
system (mainly GNU/Linux and Windows at work).  To be as independent as
possible, I use the mode-line to show information like current date and
time, jabber notifications, unread mail number, ... and I start Emacs in
full-screen.

The problem is since I use several windows (in Emacs term), these
information are duplicated and are not always visible. Indeed, the
mode-line bar is split in the middle of the information it displays.

I think it could be really great if Emacs would provide a global bar
based on the same mechanisms as the mode line but dedicated to this
kind of global information.

What is your opinion ? Is this subject already discussed before ?

Thanks,

Jérémy
