No, we are not offering CD/DVD (or any other) media protection for two reasons:
1) there is no effective media protection today. Anything can be copied with appropriate software sooner or later.
2) you should let your client make legal backup copies of installation CD's.
Your client will be able to make backup copies of your software (regardless of distribution method) but he will not we able to use it until he obtains valid activation code from you. Each computer requires different activation code.
Protected application can be distributed by any means (cd, dvd, floppy, Internet... )
