Integration Forethought over Afterthought?

DevHawk linked to a post by John Evdemon announcing an e-book from Microsoft on SOA.

From the SOA in the Real World book page:

SOA is an architectural approach to creating systems built from autonomous services. With SOA, integration becomes forethought rather than afterthought.This book introduces a set of architectural capabilities, and explores them in subsequent chapters.

Now, I haven't read the book, so take this with appropriate disclaimers of ignorance.

I, for one, would rather build on an architecture that promotes integration as an afterthought, so I don't have to think about it before hand!!!
