Following some feedback from the community, I'm happy to release version 0.5 of my vSphere License Calculator.
The main issue that has been fixed in this release is a flaw in the formula that calculates the vSphere 4 License count based on the CPU core count.
The problem was discovered when a user tried to calculate licenses based on 7 core CPUs. This had highlighted a major flaw in the original formula for calculating vSphere licenses. The formula for calculating vSphere 4 Licenses has therefore been rewritten from scratch.
Please download version 0.5 and let me know if you discover any further problems with the calculator.
The new version of tha calculator can be found here
