FreeBSD and VMWare

[YTResearch]

I noticed that someone asked questions concerning VMware on FreeBSD  
which was my first realization that the two even go together. I have  
the opportunity to advocate FreeBSD as a possible replacement to run  
that software as a parting shot in the next week prior to finally  
retiring from that organization. They are a very large windows  
operation but are putting in some Linux/VMware to reduce the windows  
server hardware platforms (I already know that this is of dubious  
value when they could natively migrate and just eliminate the  
servers, efficiency is not an option in the corporate world paradigms).

Before I actually recommend they do this on ~80 servers, I would like  
to verify that it really can be done to move to a FreeBSD 6.1 RELEASE/ 
VMware environment to support W2K3 and E2K3 on a virtual machine? Has  
anyone done this?
