I am another interested Linux user. However, as is so often the case, the company is not helping our cause. It is possible to get Procaster functioning through Wine, although it is labor intensive. By the time the great guys at Wine working on this, Joshua and Benjamin Amtzen, have it perfected, Livestream may likely take a look at what they have done and release it as a for Linux version, as has happened in the case of so much other software in the past. They don't see money in releasing for Linux, so it's probably as much a priority as promoting one of their building janitors to CFO.
