Site Licensing Model for VMWare Users

We would like to see a site licensing model made available for VMWare, or at least the same level of licensing support that is afforded RedHat hosts (e.g. 5 guests per license). We use VMWare as our virtualization backend, and it is not fair that we are being punished with 5x higher licensing costs compared with using a RedHat host. SuSe Enterprise offers unlimited licensing on VMWare, for example, and it is getting difficult to justify spending on the massive quantity of RedHat licenses.
