Need to provide atom/rss feeds of things that happen in the system - new users, new publications, etc...
Feeds need to be per user, per lab, per department, per organisation - basically, most objects in the system should probably have a /feed/update/atom type thing that will return a feed of changes when your GET it.
We can then consume those feeds for news pages in various places. This can also be subscribed to by people using feed readers and can also be consumed by a labstr mobile app.
