Lion Client/Server as Guest OS

I like to know when it is possible to virtualize Mac OS X 10.7 Lion on Paralells Server 4 for Mac

 

Theoretically it should work. I think you even can find some tutorials. But what about Mac OS EULA which doesn't give you right to install Mac OS on a "non-Apple-branded computer"? http://images.apple.com/legal/sla/docs/macosx106.pdf
