Err... dunno how you'd go about building the hardware behind this, but
assume for a moment we drag a PC into this (that puts this in my domain):
you could get a cheap multi-ADC card to accept the input from multiple
oscilloscopes positioned at various points around the target object.
It wouldn't be too difficult - about the only difficult part would be
finding/building oscilloscopes that can be hooked up to the ADC.
That's it. Problem solved. Now all that needs to be done is write the
software that analyzes it.

True enough, but how would you plot the various inputs received from each
oscilloscope? Overlay them as a single waveform like a conventional
oscilloscope? Perhaps some sort of 3D geometric arrangement? The
arrangement would all depend upon how many inputs were used.

This all reminds me of the research done in periphonics ("sphere-sound" --
surround sound is two-dimensional, while periphonics is 3D - enveloping
you on all three vectors). Periphonics uses either three or four
speakers... I can't remember which... but the arrangement of these
speakers might prove a useful clue as to how to arrange a series of
oscilloscopes around a target object.

Food for thought.
