I was on a call for VMUG leaders with a VMware executive for the express purpose of discussing the vSphere 5 licensing issue and what could be done better next time.  One of the things I suggested was that “the script” should have been available before the announcement so that instead of management down screaming about the increase in cost, it could be IT talking up (with knowledge) that the revisions would/would not be an issue.  The second was that “the script” was not something that everyone could/would run.  Ideally a plug-in to vCenter would have been the best way to go but short of that some “application” to run.  Turned out that they already had a Windows application built and released when we were on the call.  So here is a link to the tool/app and here is a link to the VMware vSphere 5 License Entitlements page.
