Yes, that's right - you can use setSerializer() to return different types of 
content from a GetQuery, including images. 

Connection management (or at least execution management) is handled by 
ExecutorService:

  
http://download.oracle.com/javase/6/docs/api/java/util/concurrent/ExecutorService.html

The default executor service will start a new thread per query, so the number 
of queries is limited only by system resources. The JDK provides additional 
executor services that you can use to manage and constrain query execution.
