I'm not sure if I overview the problem correctly. Hm, why not run the 
cable back and measure the round time? Half this time und you know the 
delay of one way. Then you can shift this with a PLL away.

A similar scheme is used in almost all modern PC clock distribution 
chips. A bunch of PLLs on the chip. Severals are available. For example 
Cypress Semi.
