This brings up some ideas I think others are having (vish I think mentioned it 
last night).

Would it be better to base when a service is up or down by something not time 
based?

Something maybe connection based, or possibly something not using absolute 
times (so that NTP sync doesn't matter).

Possibly this is getting worked on already, but can't remember, haha.

Ok. No problem!

Be careful with time synchronization. It's one of most common problem in 
distributed environments. I guess your scenario is like below:

   - Controller Node (Synchronizing from external NTP servers and at the same 
time it acts as NTP server to compute nodes)
   - Compute Nodes (Synchronizing from controller node)
