Sounds like a buy/buyback program, a SPLA and Server 200x Web are a perfect
fit, then. :-)
For a SPLA - Essentially, you just track how many licenses of x you are using a
month, report that, and write a check. Be careful with the tracking, though -
if they come audit you and your numbers are wrong, heaven help you! You're
lucky, the monthly SPLA licensing cost for Web edition is like...
~$10.00/mo/proc/instance (as of a year ago, anyways).
Sadly, I don't have any example buyback contracts on hand as I don't encounter
this problem in my current line of business. I doubt it's anything
particularly complex, though.
