I seem to remember this sort of program appearing Byte magazine (or maybe 
QST) in the early days of the "computer revolution" as a 'whatduzitdo' type 
program for hams. I seem to remember periods of 50% to 150% being used for 
timing received streams.

Oh, I hadn't heard of that scheme. Sounds like it could be a do-er though, 
but would require a fair amount of operator time. I have some old tapes of 
bits I wouldn't mind getting at, and have been considering building a little 
reader with some surface mount leads on some strip board as receivers, and a 
second set as emitters, with a small stepper or DC motor to pull the tape 
through. A suitable small PIC with UART to send it out as serial stream and 
control the motor would complete the scheme.
