yeah, you can do ethernet channel bonding. it's extremely easy to set up. with four GPUs you could get away with 2Gbps to the broker, and 1Gbps to the compute nodes.
i just ordered a 4x DDR (20Gbps) IB switch and some HCAs, so i'll be going down the IPoIB route soon. GigE is just way too slow.
most of us here use Ubuntu, because atom develops hashcat on Ubuntu and you can avoid a lot of headaches by being on the same page as him. i think most people opt for the full-blown desktop version of Ubuntu, but i like to keep things small, so so all of my systems are running a bare netinstall of Ubuntu Server 12.04 LTS. i then manually install a very minimal x11 environment, and have a standard base configuration that I apply post-installation.
