we do a lot of stuff with soap over queues (msmq in our case, but same difference) as well. as i've been interviewing people, i've observed that stuff like this is really rare, so not many people have actually stopped to think about what you could do with something like WS-Addressing and a queue based bus.

however, i totally agree with most of the rational critiques of the WS-* stack - it's gotten way too complicated and in my view simplicity has been sacrificed at the altar of XML Schema.
