I've finally gotten the time to look at this solution and it looks like 
there could be issues with multiple webapps deploying the way thermostat 
does.  I'm not a tomcat expert so I'm probably missing something, but 
here are the concerns I have:

1) With all webapps using the same configuration files, wouldn't the 
logs become a mess?  From my testing of thermostat, it places all logs 
in /usr/share/tomcat/logs with no unique extensions save a single 
exception (thermostat-web-storage).  If multiple webapps launch this 
way, won't the logs be incomprehensible?

2) What ports end up being used by these webapps if they all use the 
same configuration?  It seems like there'd be a logjam on 8005.  What 
about webapps that want to use different ports?  Is that needed/allowed? 
  Can this be done with the config file in sysconfig?
