I'm not at all sure if it's practically possible for a single (really clever) person with a high-end CPU/GPU machine (and possibly some $$$ for Cloud Computing instances), to replicate something similar to the results in this blogpost.

It's very possible.

GoogLeNet[1] is an example in Caffe: BVLC GoogLeNet in models/bvlc_googlenet: GoogLeNet trained on ILSVRC 2012, almost exactly as described in Going Deeper with Convolutions by Szegedy et al. in ILSVRC 2014. (Trained by Sergio Guadarrama @sguada)
