The issue of bringing anything like Docker (app virtualization) to RHEL/CentOS/SLC/CERN/Rocks 6.x is supporting an old kernel, adding custom-compiled kernel modules or compiling a custom one. I had this exact conversation with some clients whom I did some hypervisors work with and whom recently sold their startup to one of (VMware, Citrix, Microsoft). In fact, about 1-2 years ago we joked they should've bought dotCloud (now Docker).

PS: Docker is a prime example of how a side feature can be instrumental to a pivot to something much larger.
