Phil, It is funny they are trying to hide it. The information can be collected from free resources like job seeking portals, linkedin searches, etc. it's just a question of time one has to invest collecting this info. IBM or any other vendor can't block clients from posting jobs. As IBM claims they achieved new clients (and they publish names from time to time, like the south african bank). They should be proud they drive the world, don't they?
