This is a competing solution. DCO 2.5 architecture looks different than what was announced by VMWare/NVIDIA/Google.

DCO 2.5 works by dynamically re-allocating additional GPU/CPU/RAM resources to the VM. Overland's solution covers video performance, but is not specific to it (ie. would work for CPU or memory intensive operations too). I think DCO is a layer on top of the hypervisor. DCO 2.5 is available today.

NVIDIA GRID vGPU focuses only on video performance. The VM accesses the hardware GPU directly instead of being assigned resources by software via a hypervisor. Here's the architectural diagram on GRID vGPU:

NVIDIA GRID vGPU will be in limited preview in Q4, so this solution won't be ready probably until early/mid 2015.
