FTC Town Hall to Address Digital Rights Management Technologies - Event Takes Place Wednesday, March 25, 2009, in Seattle
I think that DRM is perfectly acceptable to be used during any sort of downloading/updating process (such as game patching.) I'm also completely fine with serial numbers used upon installation. I draw the line at limiting the number of computers/devices software is installed on, and requiring the product to be re-authorized every set period of time (like what was originally part of secuROM.) Pretty much, I'm fine with software checking validity whenever you connect to their servers, but that should be optional for people who don't have internet access.
