Description of problem:


If  I've launched a multi-tier app in the same Blueprint I can pass the address of the db server to the middleware server and the address of the middleware server to the web servers.  

If after time I want notice the webservers are highly loaded and I want to launch an additional instances to take some of the load,  I'd like it to be able to get the address of the middleware server, which should still be available at the config server.

I see that scoping could become an issue, saying that if I launch multiple instance of the same multi-teir blueprint, I am not sure how you could resolve which Application group to get teh variables from.  Since the Application is names at launch, it could be use to uniqueness, however it is changeable a launch so scripting to the variable may pose an issue.
