Licensing FileMaker now boils down to the following rule: Paid client (FileMaker Pro) means free server and free client (desktop browser or FileMaker Go on iPad/iPhone) means paid server

Free iOS clients, but no Android client

The new paid server options come through purchasing user concurrency packs that determine how many free clients can be connected to the server at one time

So imagine how powerful it would be to be able to develop and deploy multi-user solutions, without caring whether the clients or even the server was Windows or Mac?It gets better: The mobile client, FileMaker Go, is free
