Licensing - What happens when you go over?

Hi All,

Just wondering what happens when you go over your concurrent number of licenses?

We are currently running thin apps in a pilot project with 20 licenses.  We want users to give it a test drive but are wondering what happens when the 21ist person tries it?  Do they see an error?  Is it only in the logs?  Are they prevented for opening an app?

I see under product licensing and usage the highest total concurrent connections is where I can monitor total connections but even something that shows me a graph of overall usage would be more useful?

Thanks.
