Recently I been helping Michael Stephenson on his article about BizTalk RFID and NServiceBus, which is published on Microsoft technet WIKI site,
http://social.technet.microsoft.com/wiki/contents/articles/biztalk-2010-amp-nservicebus.aspx
The article is mainly focused on how you can take advantage of NServiceBus along with BizTalk RFID capabilities on high volume scenarios, where you don’t want to waste BizTalk processing power for just routing from A to B.
Nandri!
