Create sites which you can't leave or close? Easy, use drm and prevent any action that would closing the tab or give access to the url bar.
DRM is code with the intention to take full control over a device after sale. With that, any action is possible. Installing tool-bars, sending browser history, stealing information. The only protection is the letter of the law, and any hacker brave enough to reverse engineer the drm to identify what it actually do (under the threat of DMCA and jail time of course).
