Here’s a list of resources I think are worth checking out. Not all pertain to SPLA specifically, but in the world of IT – all licensing programs find a way to relate to one another. Check it out.
Microsoft SPLA Program
Microsoft Marketing Campaigns
Great Microsoft Volume Licensing Blog
SPLA Reseller (I work for them with SAM) There is a free compliance check where the team will review your order and ensure you are licensing correctly and the most cost effective way. http://www.softwareone.com/en-us/Licensing/Microsoft-SPLA/Pages/default.aspx

VMware Service Provider Program
