Hi

This CAL licensing stuff is making me crazt so I have a CAL question for you experts:

If I have a SQL Server Standard with transactional replication set up to replicate a database to 3 SQL Server Express (1 publication, 3 push subscriptions). Each of these servers is on a seperate computer, connected together with LAN but none of them is in a domain.

Now each of the 3 Express servers is a kind of a "server" for a group of computers. Let's say for ease of calculation that 3 computers connect to each Express server.

The big question is:

Do I need to pay 3 CAL licenses, one for each Express server that is connected via replication to the Standard server or do I need to pay 9 (3*3) CAL licenses. One for each computer that connects to the Express servers.

The license agreement speaks of "Multiplexing devices". Is SQL Server Express considered a multiplexing device?

You should contact your local Microsoft rep to be sure, but from my understanding SQL Express does not require any license for use. It just has limits on database size, features, etc.
