Get ifup/down scripts to restart relay whenever an interface changes state ?

Do you mean a subset of your interfaces, or all of them ? If you mean 
all of them then I believe your start the relay without specifying 
any interfaces and it will listen on all of them. If you really do 
mean a subset of active interfaces, then again, get your ifup/down 
scripts to call something that will enumerate all the interfaces and 
start the relay with the ones you want and which are up.

That's all I can think of.
