When you are working with NAV 2013, you are using one license.
1) If you send to excel something, do you need one license more?
2) If you want to see how many persons are working with NAV, do you need one license more?
A work-around for finding which users are logged in without using a license is to run this query from SQL Management Studio:
SELECT * FROM [Active Session]
(I haven't found a reliable way to get the actual SQL process ID for a specific NAV user in mgmt studio yet - that would make it easy to disconnect specific users from mgmt studio if required).
