In some business sectors I see increasing demand for bottom-up-open-stack, going as far as inquiring about "Open-Firmware-no-BLOB" computing devices for all important tasks, including network and domain control, where "legacy client application systems like Windows/Outlook/Office" are relegated to isolated TS-Servers, and are being replaced by glorified thin-clients, with a local browser, media-decoder, and RDP-RemoteApp-client, all running open stack. Currently the problem here is the availability of ARM system with user-configurable TrustZone support.

But O.K., I admit, we also have a lot businesses wanting less paranoid data security practices for the sake of convenience, or other legacy Apps/Hardware.
