The problem is, while OT itself is an open spec with open source implementations, it uses ideas which are patented elsewhere. That's the unfortunate minefield in video specs... there's no novel/unique approaches out there, and every way to handle it is patented. So even though OT looks like a "safe" codec, it is liable to get nailed at any time with a patent suit, for right or wrong. In a twisted, sick way, H264 is actually safer by virtue of the fact that the patents are pooled and the tech can be licensed to begin with. Once you get the H264 license, there is no fear of lawsuit. So on one hand, you have H264 and the costs associated with it, and on the other hand you have OT with no fees but the *potential* to get blown out of the water. No matter how you cut it, it is a bad scenario.
