Number of users online / Who is online We have a site that is running event pages, that will show live content (via Ustream or similar). Users have to be reg'd and logged in to view content. 

We would like to establish who is online and how many logged in viewers at the time of the event. Is there a function that will display this to admin users?

Thanks
Dan
I have added a prototype plugin that uses Pusher.com to keep track of online users.

Check out the Git repo.

Basically you need to add this to your frontend template:

{{ craft.whosaround.setup }}


It adds the Pusher library, and also subscribes to the channel name you got in your settings. You need to signup to an account over at Pusher.com as well.

In the CP, you can get a rudimentary list with the name and the count.

I can think of some cool use cases, so I'll probably revisit it soon and add more stuff etc., but it might be a useful starting point, depending on if you want to use Pusher for this.

Pusher is a very neat service for use cases like this, and might be especially interesting if you expect many users online.
