The convention for a unique clipboard is to manage the selection
CLIPBOARD_MANAGER.  The details of this are in the ICCCM. The source
code of xclipboard (kinda), FVWM, Metacity, any xsettings daemon, any
freedesktop.org-compliant system tray (e.g., eggtray), and the
simpleclipbook program (which I showed you) all contain examples of
of selection managers.

(xclipboard's is actually deficient. IIRC, it doesn't send the appropriate
ClientMessage to the root window and doesn't support all required targets.)

simpleclipbook and xclipboard used to correctly interact with each other 
and themselves, but the simpleclipbook code was written before Gtk2 stabilized.
For example, it still uses gdk_send_xevent() which is no longer in the API.
