I am really interested in seeing if we can standardize on Raspberry Pis as the Official Public Node of NXT and deploy a lot of those all over the world rather than renew a bunch of more expensive VPSs that got us thru the initial late Dec crunch.  I have heard different things about it - it can definitely forge blocks, it's underpowered for the task, it works better if you plug a thumb drive in the USB port to give it more memory, it needs to be replaced by a Cubie.  I would like to pull all this together and come up with a definitive answer on a Raspberry config that is qualified to be a Service Node without running out of horsepower.  Dave, your thoughts?
