I am VERY aware of how much we spend on licensing. Volume licensing is simply a means to simplify license management. One key to rule them all, in a way. And our pricing is not obfuscated at all. Microsoft is very up front with us on how much it costs use per server/seat.
I don't mean to start a flame war; Not everyone gets the same deal. It's the customer's responsibility to make sure their side of a mutually beneficial deal is in fact beneficial. But if you don't have a lot of market power as compared to the vendor you may wind up adapting a bit in order to get the deal.
Of course they don't want you to *feel* bad about the deal...heheh.
