To keep this short, I will simply state that DRM does very little to hinder the people it is attempting to halt ('pirates,' people who steal intellectual property) and places more of a burden on those people who it wishes to protect (the creators of whatever the product is and the consumer). I understand many developers, especially those in the software and video game industry, think of DRM as a means to keep their IP safe, not dissimilar to locking your car or house. However, this analogy falls apart quickly. If I could only unlock my car five separate times (see Bioshock), it wouldn't be doing me much good at all. If I could only park it at five separate locations, then what would happen if I moved and had nowhere to park (reinstalling software on a new computer/HDD)? The only DRM I have found to be rewarding to any party (excluding thieves), in terms of software, is that of Steam, created by Valve. I highly suggest you look into it and, if you do continue on with this assault against paying customers, attempt to learn from it.
