Since #phosh made lockscreen widgets a plugin, I actually found it is prettty easy to make one yourself! I have been playing around with one that displays emergency info and emergency contacts.
Is there anything obvious I am missing from it? I got these from Android. Note that a user can add/remove/edit Emergency Contacts as they wish. (My hope is to merge this back into Phosh proper).

It's in Phosh directly. You enable it with phosh-mobile-settings. I can't find the demo for it off hand.
