It's great to see you guys pumping out CTPs every month now, the innovation and stabilization rates is something I appreciate.

I am looking for some good samples on how to do chunked binary transfer that uses WS-ReliableMessaging and WS-Security (body-encryption) together with MTOM.

Right now I have a service interface that takes a Stream type, but as far as I can see it's using a default behaviour of buffering and transfering the whole data in a single message.

I read Yassers latest post on "Moving lots of data" and downloaded his PDC sample from WindowsCommunication.NET, but that seems to implement a custom channel for chunking, but his blog post makes it sound like there is built in support for chunking in WCF?

Working on a prototype for a new product which involves transfering (synchronization) files between two servers, in a reliable and secure manner on networks that range from unstable and low-bandwidth (dialup/satelite) to fiberoptic broadband connections.

Got any good references for MTOM+WS-RM+WS-Sec? :)

(Hopefully I will meet you at Connect Event 2006 in France in 3 weeks time)
