Redmine

We were looking for a way to send reminders that are due date not only to assignees but also to watchers and authors.
Finally I came up with a patch to redmine that adds this functionality without changing any old one.

It patches
app/models/mailer.rb

adds views into
app/view/mailer

and adds some locales
We would much like to see this in future versions
I named some usecase in http://www.redmine.org/boards/2/topics/16244
