Events as post collections

I would like to create a system that that allows the creation of an event. This event whilst being managed as a calender event, would also act as a collection of posts that relate to that event.

For example, and event in the diary is created that represented a camping holiday, I would like to have that event show up in my calender so people could see when it was coming, and I could also make posts about what I want to do when I get there, what I am doing when I am there, and how I feel now I am back. In this way the Event acts as a collection of content with date relevance.

I understand that this functionality is implied in the normal structure of a blog, however this is to be implemented on a multiple user blog, where many events my be going on concurrently, and posts are made about them by numerous people. Accessing content associated a specific event would allow for a much more coherent experience.

Is there a plug-in that would allow for this?

Is this something that could be developed?
