Real world trials generally don't use placebos. Instead, the control is the best treatment currently available. After all, you're usually not interested in whether some drug works better than sugar, but whether it's worth using it instead of or in addition to some currently available treatment. So the control group get the best treatment they could have got if they were not in the study, while the experimental group may or may not fare better.
The needs of the many outweigh the needs of the one. Getting clean data for evidence-based-medicine is absolutely necessary for the well-being of possibly thousands or millions of potential patients.
We already have an unpatented, royalty-free, unencumbered, lowest-common-denominator video codec for use on the internet: H.261.
H.323 specifies it as the lowest common denominator for video-over-IP, so all video phones already support it, including hardware implementations. It was published in 1990 - twenty years ago - so it is as patent-free as you can get. And it's published by the ITU, so the specification is freely available.
When you don't know what you are doing, do it neatly.
