Don't get me wrong here. I've nothing against beeping applications. I'm 
using beep myself to signal when my headless computer has finished 
booting. And I love old DOS games that beep around as if there's no 
tomorrow :D

The problem is that the beep "control interface" on *nix platforms seems 
to be integrated into the terminal system. And I don't want any 
application to fiddle around with the settings of the devices that 
belong to that system (especially without my knowledge).
Better would be if there'd be a beep device (e.g. /dev/beep) which could 
be owned by a group "beep" or maybe the existing "audio" group and thus 
all would be happy...
