Federal Express, the high-speed shipping company that seems to have mastered the logistics problem.
They have the second largest airfleet in the world. Their central exchange is in Memphis (?). Often, it is faster for them to fly something hundreds of kilometres to Memphis and then back to a nearby city than to go from city to city directly.
They are a ColoradoSpringsJavaCompanies member.
They are supposedly a large GemStone customer.
I was working with one of FedEx's vendors for the Colorado Springs operation recently. They have a lot of SmalltalkLanguage code, but this is being phased out. :( -- AnonymousDonor
