They all seem impossible to pull off in anything but lab controlled
conditions.
Not at all. I've seen clearly with my own eyes the image of one
persons VT100 CRT tube appearing on another across the room because
the ground shielding had disconnected. If you have a high gain YAGI
antenna, digital RF buffers and some fancy modern DSP lord only knows
what you can snoop through the walls.
Most of this is solved by having a simple metal (steel) PC case and
grounding the PSU though. Use good quality cables with FCC/IEC badges
not the bargain bucket Chinese ones.
