This looks really good. I have been trying it out, but the assumption about
HiveMind being already initiated is tripping me up. When the bean is
creating, the HiveMind registry hasn't been created yet. So I am trying to
either delay the lookup in the bean, or force HiveMind to come up first. No
luck yet.
In my web.xml, I have a context listener set up for
org.springframework.web.context.ContextLoaderListener. I am thinking that I
will need to create a new context listener for starting HiveMind before
spring.

I think you can replace thier RegistryFactoryBean with the following
and still use thier ServiceFactoryBeans. (whipped this up, it's
untested)
