I would suggest that Bob visits his optician, for there are many open-source industry-specific enterprise applications out there, should he care to look.
In Healthcare IT two high-quality FOSS enterprise applications that I've come across recently are Mirth ( http://www.mirthproject.org/ ) a cross-platform standards-compliant interface engine, and Tolven ( http://www.tolvenhealth.com/ ) an EHR solution.
I can't comment about other verticals, but I suggest that the parable of 'look, and ye shall find' is appropriate here.
