Little lumped-constant delays I doubt could hold more than 1 - 3 bits,
with a big bag of support logic.

But, you could play with one with an o'scope. DL's require correct
termination impedance, often 50 ohms. You put a (say) 10nS pulse in one
end, and it appears, delayed by more-than-the-speed-of-light, at the
other end. If you don't get the terminating impedances correct the pulse
will reflect and mess it up (the pulse, that is).
