The COLO effort is driven mainly by Intel China and they are currently deploying it at some Chinese cloud provider AFAIK.
Unfortunately, as cool as VMWare FT and QEMU COLO are, you need high-bandwith and low-latency links between the nodes and still they increase latency and reduce performance a lot. And in 99.99% of cases just replicating the disk and restarting the VMs in case of a node failure is good enough.
