Code, only the code[0][1] :-)  Basically, you set an XSelection inside
your plugin, and you can get the XSelection in other processes.  When
you get the XSelection, you can write messages to it.  Just like it
would work with a common Socket where you take care for new input, you
do it with GLib signals.  You listen for new messages.

Let me factorize what you can share between different plugins: a
set_selection function that takes a "selection_name" (your plugin name),
a "callback", and a "user data" for the callback (a pointer on your
plugin).  And thats it.  Well then you have the popup command, where you
can share code for the check_is_running function…

IMHO, I'm not sure that a selection thing should end in libpanel.  There
are tons of ways to do this.  First idea that seems nice is a general
popup command (e.g. `xfce4-panel-popup plugin-name ...`), with a "popup"
signal to attach to inside the panel plugin interface.

static gboolean        popup_callback        (XfcePanelPlugin *panel_plugin,
                                              gchar ***argv,
                                              gpointer user_data);

That's what I can think of now… but there is maybe a 4.6 way.
