Hub and Spoke or Message Bus Architectures are as legacy as tape and vinyl

Philosophy was never my strong point (although I can tell you anything you need about electrophilic reactions of osmabenzenes). 

Anyways where was I. Hub and Spoke versus Message Bus has been a long standing philosophical discussion. Well why chose one or the other when you can chose both? That's what we did with BizTalk Server 2004 taking the best of both worlds and putting them together with the specific scenario of integration in mind.  I recommend that everyone reads this document to see what I mean.

Btw. Thanks to everyone for coming along to the Belgium Launch event. We had a lot of fun and it was just fabulous to talk to so many customers using the product in cool ways.
