Well, I'm always amused to see that the Oracle client installer still checks if your monitor at least supports 256 colors :)
Their licensing model: if you hire a single spot in a parking garage with a capacity of 500 parkings, they'll charge you 500 licenses. Their philosophy to justify this, is that "you might have parked in any of those 500 spots".
@Olan, hats off if you got to understand the license fee. We came to the conclusion that to be on the safe side, we'd have to PAY for a consultant to explain the licensing model to us. Of course we didn't and still got someone from Oracle to explain the model (hence the analogy with the parking garage). There's too many gray areas.
