It sounds like Microsoft's Consulting Services has extended  Mr.Walker's OR-LOS for Commercial Lending.  If you have the time (28 minutes) its worth a look but my overall impression is this could only be useful for a supper huge bank/lender that has the IT staff to pull it off otherwise its just overly complicated.  The question still remains how scalable and dependable this framework would be.

Also according to Mr. Walker Microsoft will increase its participation with industry standards ( ie MISMO)
