I think DRM solutions suck.
Necessary in some cases, but all I've seen suck: They all don't work in all instances, like an un-DRM'd video. They're a pain in the ass to implement. Etc. Etc. It's almost as horrible as developing content for wireless, which is even a bigger nightmare.
However, I'll give props to ObjectCube ( 
www.objectcube.com ) for trying their best at providing DRM solutions.
