dbus library functions

[Mark A. Hershberger]

I'm interested in making a library of common dbus services available in
Emacs.

Three logical services would be Notify, On Screen Display, and Avahi.
Perhaps some of the power management information available via DBus
would be useful to battery.el, as well.

So, two questions:

1. Would building Emacs Lisp functions to encapsulate some of the DBus
   information be useful to include in the core?

2. Would it be better to create separate libraries (e.g. notify.el,
   osd.el, avahi.el) or a single one (e.g. freedesktop-dbus.el) for
   these functions?

Thanks,

Mark.
