Not sure if I really understand your question but FUSE Mediation Router 1.5 is basically Camel 1.5.
Why do you want to integrate the two?
FUSE Mediation Router is the FUSE enterprise version of Apache Camel.
See more here:
Apache Camel 2.0 has not been released yet. There is a 2.0m1 = the first milestone release.
We expect Apache Camel 2.0 to be released in Q2 2009.
FUSE MR 2.0 is released after Apache Camel 2.0, as its of course based on it.
Thanks and Regards
Maybe you should try out the Fuse Mediation Route 2.x-fuse-SNAPSHOT, which is synchronized with Apache Camel 2.0-SNAPSHOT.
