If someone is going to implement this logic, I'd like to see it 
generalized slightly differently.  I'd allow adding group or tag names 
to each host, then have some additional settings that apply to the 
groups, like the permitted concurrent backups of members of the same 
group to control bandwidth out each network branch.  Perhaps there could 
be group-specific overrides of the config variables as well as 
host-specific to easily control things like enabling ssh compression or 
setting bwlimit.
