More info on SMP

The maintenance plan is only available for the commercial version of the mendelson AS4 software, and can only be purchased as part of a bundle with a current mendelson AS4 software product. If you license more than one product it is required that all have either a SMP or no SMP.

Desktop application vs Client-Server application

The community edition of the mendelson AS4 server has an included graphical user interface and could therefor not be started in a dedicated server environment (mainly linux without an installed X environment).

The commercial edition contains a server installation and a client (graphical user interface) installation with works cross platform. You could for example run the server on your linux server and attach several clients to it from any windows desktop with a single license and user management/login. To fit the productive requirements of your communication the commercial version of the server installation could be started as windows service.
