I guess the BizTalk Server 2006 CTP (Community Technical Preview) version will be distributed to TechEd 2005 attendees. I used be involved in a customer program introducing BizTalk Server 2006 to real customers. When they faced the major features of BizTalk Server 2006, they surely seemed to be quite satisfied with the enhanced features of the management, BAM, FF wizard, and so on. I hope you could get same feelings with the CTP version sooner or later. And..you will surely need this installation guide of the CTP version after getting the real software.
