Can Python and DISCO be installed easily on a Rocks 6.2 cluster?

Question

I'm looking for a way to quickly and easily build a compute cluster using cheap pcs (all identical hardware). Rocks looks like a possible solution, but I need to be able to run Python 3.4 programs on the nodes, and need to set up DISCO on the system as well. Is this possible to do with Rocks, or am I better off just setting up one cluster for DISCO stuff, and an entirely different one for traditional MPI based computing? Ease of set-up is a big concern here.
