[vbox-dev] VirtualBox Extension Pack going GPL?

I would be interested in the VRDP piece as well and contributing to the 
cost of developing/purchasing it.

Citrix just open sourced XenServer, the whole stack, there is no 
difference now between the commercial offering and the open source 
version; except for support.

Redhat's KVM hypervisor is open.

Here is hoping that one day Oracle releases VRDP under an open source 
license.  As Pau writes below, you can't buy an OEM version; therefore 
they aren't monetizing it on the server side, except for their Secure 
Global Desktop.
