There are various ways. Maybe require explicit signalling from the user 
via some command to the control-plane tools (start up my domain / shut 
down my domain). You could also do it implicitly (although it may 
require some iptables hacking) by tracking network connections to the 
domain's IP address -- start it up on first connection / shut it down 
when last connection finishes.
