There is an extension called DBusBird for songbird (the music player
based on mozilla), which starts a DBus server so scripts can query the
currently playing song info. This extension uses IDL to describe an
interface which the mozilla JavaScript API can use to call into C++
code. The compiled extension contains a Javascript file and a .so binary
which is loaded when the JavaScript requests the interface name
("@mozilla.org/DBusbird;1"). The C++ module links to the dbus glib
bindings, and does all the dbus stuff with the info it gets from
JavaScript.

If the browser dbus bridge is stable enough we could do everything in
JavaScript. Otherwise a simple wrapper in C++ based on the dbusbird code
might be the best way to go.

Due to a missing pyxpcom package in ubuntu karmic the firefox extension was hacked by files in the dbus communication process. this is VERY inefficient. We should use XPCOM instead.
