The way the MDCS licencing works is per worker process. So, if you wish to run
16 workers, you'll need 16 licences.

You can mix these things (I'm not 100% sure, but I think you'd be best off
installing MDCS separately on the machines as the licencing is different) -
i.e. it's fine to run a MATLAB+PCT as well as the MDCS workers on a single
machine (internally, that's how we do a fair bit of our testing).

Cheers,

Edric.
