The Virtues of PatientOS

It used to be a truism that the open source development methodology would only work for mainstream projects. Only for areas of interest to large user and hacker populations, so the logic went, could support the free software ecology. So a striking proof of the growing maturity of open source is its increasing appearance in vertical markets, hitherto regarded as unviable.

For example, here's the GPL'd PatientOS:

PatientOS is a free clinical information management system for hospitals and healthcare practitioners. Pharmacy, the laboratory, registration and other departments will be able to automate many processes when version 1.0 is released October 31st, 2008. A physician practice version will be released March 31st, 2008.

Pretty specialist - and pretty important, too. (Via FSDaily.)
