Also if you just need  a high level of syncronization between the time on 
all your hosts you can just deploy one standalone ntp server, sync it 
against public time sources and get everything synced against that. its 
probably a 95% solution to most people's timeing needs.


If I recall correctly, NTP assumes that latency = RTT/2.  You might 
make it work well for his application *if* you set up your tree so that 
your paths are each one hop, or at least symmetric over your network.

Correct, and if it's asymetric you get a static offset. My laptops
internal clock is a bigger source of error...
