In an interview to Stefan Tilkov, Arjen Poutsma, of Spring Web Services fame, had something nice to say about SSDL :-) Wouldn't it be great if there were frameworks out there providing support for SSDL-like contract languages? I have been hard at evangelising SSDL within my company. Let's see if anything comes out of it (btw... I have no insight into any future product plans so don't take this post as any kind of indication of what's coming). I've even built a XAML-based and WF-driven contract language to illustrate the advantages to customers.
