I see you price ES as follows:

Just confirming a "CAL" is a "Client Access License" on a per-user concurrent basis (not per-device and not total user count).

So with the smallest package, MyApp could have 100 total users, but only a maximum of 25 could be logged in at any time from any machine. 

Thanks,

Just reading the MS SQL definition of a "User CAL" and it appears that they do not mean "concurrent" but "total" users.

You are correct it your latter post.  This CAL is the same as SQL Server, which makes sense since the ES server when using a SQL or other database CAL must respect those terms as well, even though there is really only one machine talking to the SQL Server database.  You need one CAL for each user that will be talking to the ES server in total.

Thanks for the clarification.  Makes sense.
