Well I'm running 3 coda servers.. one of which is outside my firewall and 
behind it's own firewall.

Soon I'll add a 4th server, also behind it's own firewall.

"Co-Located" probably isn't really the definition you mean. I suspect "well 
connected" is a better requirement, in which case the number of 
intervening firewalls shouldn't really matter. So long as the connectivity is 

In my case, it's good.. but I also need firewall security at both locations.
