Hi Bill,
what about White Rabbit?


Successor of NTP.. PTP: precision time protocol.

It delivers Gigabit Ethernet and precise (<1nsec) timing over singlemode 
fiber. You would have to connect all devices into a fiber network 
instead of a copper based network and all switches in between would have 
to be WR compatible.. but this could solve your problem.

Javier Serrano (one of the developers) is also on this list.. he might 
add/correct me.
