@solid,
To see many "sample configurations" clone spring integration samples project: "git://git.springsource.org/spring-integration/samples.git" from http://git.springsource.org/spring-integration/samples
Since Spring Integration is just "pipe --> filter --> pipe", you should definitely be able to "transform" message payload ( you data ) as it travels from one pipe ( channel ) to another.

Humans are stateful and mutable beings that have no problems processing many things concurrently and share state with others + they are usually "coupled"
