The original article inspired me to get a retina ipad and wireless keyboard with hopes of connecting to my home server and developing with issh/tmux/vim/chrome and working anywhere from my tethered 4g phone. It was an immediate disappointment: issh is extremely unreliable, has awkward rendering glitches and a UI that can't be configured to actually fullscreen. Oh and it times out after a short while, especially if you've switched to some other app. iOS can't remap caps lock to control either, which would have otherwise made it usable for me. I didn't waste any more time attempting to fix these issues; the only way I see this working perfectly is if I had actual linux running on the ipad.
