Guys,

you have agree to integration style that keeps two potential solutions, 
Hive/Spring, leaves final decision to users. I'm fine on this agreement.

but do you have comprehensive design schema, I think the topic discussion is 
not closing in jira, we should keep in same page about event/message/sync/async 
details.

thanks

Sounds good to me.

You can implement your preferred hive-style, I can implement spring
integration based on your interface.
