Is that not how many businesses and government purchase enterprise licenses of Microsoft software?
In addition to this it seems to be common to purchase one license with hardware and a second license for the same software (but potentially a different edition) from a dealer.
Absolutely. I've been trying to buy KMS license for MS Project for 10 users on a Terminal Server farm with 100 KMS licensed Office Professional users. It's been a month-long nightmare already. I've bought two cars within 2 hours each.
