My client is asking the application on CD and exe only where we are giving only five cds
But at my clients place there are 250 systems and he is not wanting to give us the mac ids too so i thought one dongle to one cd where he need to plug in to a system to run the exe else i have a fear of the cds getting copied
Any alternative to this solution

Dongle is a bad way to build an applications. Not too many people like to use an external hardware these days. Why don't you use a product key approach. If you are concerned about people copying the key, you can build a one-activation-one-time-only approach.
