Well, how complex? Front end with a fast ADC and make a DSP DMTD device?

In terms of simpler things that (AFAIK) one can't go out and buy:  a
TIC with 4 or 8 inputs would be an interesting piece of time nut
gear.even if it was 'just' 1ns resolution

Surplus lab TICs are easily had but become quite a pile of equipment
when you want to concurrently measure a half dozen oscillators.
