Good thinking.

There should only be one hop, and make that a layer 2 hop, between the 
multicast server and the systems.  A 10ms delay through an IP router 
could impact the whole sync process.  Again there IS 802.1 bridging 
designed for this; I could look it up if needed as I once did 802.1 
standards, but now  do 802.15 stuff...

In IPv6 you could use anycasts instead, and this is an example of what 
anycasts were designed for.
