"i don't think that the performance degradation due to XML payload is really significant for most business applications, unless ofcourse you are building a real-time system that has to handle thousands of messages/sec"

Daily tracking of tens of millions of FedEx shipments
Daily orders and replenishment of Walmart inventory

I work everyday with this kind of scenarios, millions over millions of transactions, and it will be hard to replace EDI unless there is a better format and XML unfortunately sucks in this area.

Compare an invoice in EDI with its XML counterpart and you will understand why sending thousands of XML documents per hour would be a great mistake.

"Wouldn't it be better that the wire-format can be chosen using policy assertions?"
NOW we are talking...
Looks like we've finally seen the light at the end of the tunnel.

I understand your concerns. It is a typical 80/20 scenario. But, even if you take your case, web services based design should work with out much difficulty.

Let's do a little math. Let's say that you want to process a million transaction over a period of 10 hours (I am not assuming batch processing here). That boils down to processing ~28 requests per second. If you have sufficient network bandwidth, this is not something that sounds imposing. Assuming that the processing is not CPU intensive(which is usually the case), a decent server can handle this load.

Of course, if you want to process more messages (let's say 100-150) during peak time, scale-out architecture of web services can be helpful in processing more messages. Only constraint in that case would be network bandwidth.

It would be great if you can share the summary of your benchmark results.

Design in SOA is pretty much functional decomposition of the architecture. At the lowest level - programming - SOA says very little, and coexists with OO perfectly

"i don't think that the performance degradation due to XML payload is really significant for most business applications, unless ofcourse you are building a real-time system that has to handle thousands of messages/sec. " What makes up the XML payload that causes performance degradation? My problem is SQL searches that return fast when initially run, then slow as the day goes on. Does the "XML payload" have anything to do with this?
