I maintain openpgp-applet [0] (both upstream and in debian, which is in perl / gtk3 and currently uses the old fashion systray. However, I did a quick search, and I couldn't find the bindings for perl you speak about, be it on CPAN or Launchpad.

I remember reading somewhere that a limitation is that you can only use one type of click (no way to behave differently on right-click / left-click), so I guess in some cases the switch means also a new UI, right ?
