Recently, I helped organize and speak at the first national conference on VSED. It was held at Seattle University October 14-15, 2016. About 225 people attended, mostly professionals. The conference was excellent.
If you go to http://www.phyllisshacter.com/the-story/1st-national-conference-vsed/ you can read the article about the conference.
This article by Norman Cantor is worth reading about various ethical perspectives about VSED. It’s difficult for me personally to think that a court could uphold and go against someone end of life wishes. We have to be vigilant about our rights. This can be a slippery slope.
