Loosehead Prop writes "A U.K. startup called Streamburst has a novel idea: selling downloadable video with watermarks instead of DRM. The system works by adding a 5-second intro to each download that shows the name of the person who bought the movie along with something like a watermark: 'it's not technically a watermark in the usual sense of that term, but the encoding process does strip out a unique series of bits from the file. The missing information is a minuscule portion of the overall file that does not affect video quality, according to Bjarnason, but does allow the company to discover who purchased a particular file.' The goal is to 'make people accountable for their actions without artificially restricting those actions.'"
