App events

[tj]

will brainstorm some practical ideas but might be good
to have the app itself emit some events

[masylum]

I would like to have events on matching routes, so you could emulate before_filter.
This could be useful to load a user from the session, or just to setup the layout on a view.

Another useful event could be, on render.

I would call those hooks more than events, still useful though since they would alter the flow. I will create another issue about getting before() back in possibly

[tj]

gonna close this until I have a use-case

[ghost]

a use-case I actually have is to update a What's New box (in a ajaxy way) whenener my webapp gets a new feature and notify the user of the update (with a growl-like jquery plugin)

the "What's New" contents could be stored in a view file that, when updated, would automatically have its data broadcasted to the clients

sounds good?
