According to my crack team of researchers, to be a successful ILS/OPAC salesperson you need to be:
- Nice personality. Blond highlights helpful.
- Speak with a cool sounding accent. Double marks for Australian, mate.
- MOST IMPORTANT: You have to buy lunch for the staff.
I think this pretty much sums up why open-source ILS systems aren't very popular - free software, but no free lunches.
