I just sent off an email with my questions regarding Ven. Jinghui's Heart Sutra commentary to someone at Dharma Drum. It wasn't a complete list of questions, but is a start, and will give me some idea of how much help is available.
Many of you may alread know, but Chan Master Foyuan passed away several months ago. He was a direct disciple fo Empty Cloud, and was highly regarded within China. Let's hope he comes back soon, and continues his work of trying to englighten us all.
