and i have another functionality add on, a history table feature which i wrote for wikitimetable.
I will continue coming up with a scheme to be able to plug things like this in. I got dragged off WT to do something that might actually make money, but as a result i can now have a leaflet map editor that will distribute your edits live to someone else looking at the same place. all using the standard stuff, including a genuine leaflet marionette view (i.e not one which uses geoJSON which isnt really getting us anywhere) which is perhaps overkill but pretty awesome all the same.
may be
sequelize.applyModule(require('sequelize-notifier'))
to be applied after you've set your models up but before sync.
