Hi David

Here's a little dirty secret:

WiFiDog does not require a WiFi connection.  It simply works on  
"interfaces".  If you can get all your internal traffic coming in  
through something that linux can present as an interface (ethernet,  
wifi, bridge, tunnel, etc..), WiFiDog can control it.

So yes, you can have 1 WiFiDog installation with multiple child  
routers that chain up to the main router running WiFiDog.  As long as  
they're all presented at the main router as one interface, there's no  
problem.

The only gotcha to this scenario is NAT.  WiFiDog distinguishes an  
individual user by, among several things, their internal IP address.   
If one of the child routers has NAT enabled, hence presenting to the  
parent router all it's end-user's traffic as a single IP instead of  
by their true unique IP addresses, WiFiDog will not work well in that  
scenario.
