I've added a section called SOA Patterns on the site while holds the current draft for the table of contents of the SOA Patterns book I am writing. The section lists the problem each pattern addresses as well as links to published patterns. Also, you can  use this to monitor my progress (patterns that already have their problem written down already have drafts; the others are in-progress or not started).

I am currently working on chapter 4: Security & Manageability patterns (not counting delays mentioned in the previous post).

Also, as I think I've already mentioned, I'll make public at least one pattern per month, if you are interested in a specific pattern in particular (from those which are ready - now chapters 2&3) drop me a note and I'll publish the one that gets the most votes
