Mind-bending WSE

I’ve been playing around with WSE a great deal lately. After a long evening of playing around, looking at packet captures, reading doco etc I crawled into bed. I had strange dreams of messages flying around. One message opened and a wizard-like figure came out. He asked me if I wanted to “join a Kerberos realm”. Very strange. I’ve noticed that in all the WSE samples the client and server both reference one or more “shared”/”base” projects. I can understand that this is (presumably) to make the samples smaller/more uniform, but doesn’t it go against the tennent of “sharing schema, not type”? After a night of looking at the Custom Xml Security Token sample who knows what strange dreams await me.
