I saw a few people requesting something similar to this, and I also had a need for the exact same thing and couldnt find what I wanted, so I coded this plugin.
Details : You nominate a Category (or categories) for your event posts. Install the plugin, use the future posts hack and posts in the event category will be displayed on your site where you select to display it. The ability to hide all posts from the selected category is also available to keep them off the main page.
An example can be seen on my DevBlog here http://revolutionx.net/blogs/devblog under the heading Events
Any feedback on this plugin is welcomed. I still have some work to do on it, but if there are any suggestions/requests to add to it, let me know.
