Salon.com on Open Source Medical Software

mke writes "Life or death software; new medical programs show the strengths of open-source coding -- and its weaknesses." One of the biggest weaknesses mentioned in the article is that there's no software company to sue if something in the code kills or injures a patient. Another problem, at least in the U.S., is that FDA approval for medical software costs millions. The question is, can these problems be overcome, or will proprietary software continue to be the norm in critical medical applications?
