*Is*: it's singular. It comes from "d", short for "desktop", and "bus",
short for "omnibus", which comes from the Latin "omnibus" meaning "to or
for, by, with or from everybody" which is a very good description!
It's a piece of software with associated bindings that allows software
to "broadcast" information to none, one or more "listeners", and for
those "listeners" to respond.
Imagine that a USB scanner is plugged in. One listener might be
responsible for creating a device node and giving it suitable
permissions for any currently logged-in users. Another might potentially
show an icon somewhere in the desktop environment. I don't think xsane
currently listens to dbus, but it could be adapted so that it
automatically realises that a new scanner has been plugged in.

Hope this helps,
