My assumption is that the company would have to assume responsibility for all state mandated procedures OR the hospital would deep freeze the placenta (as is currently done) and then instead of sending to be incinerated it would be sent to the company. It's an important detail but they would have had to address the topic somehow to have gotten this far.
Actually the diciest part of the consent IMO is the extra tube of blood (sounds ridiculous but you wouldn't believe how squeamish some folks are) and the release of medical information. I think hospitals would want to tighten that clause up a bit but still seems like a viable framework.
