This week Hostbridge published a case study about a project I worked on at my previous employer. The cool thing is they quoted me in it. Hostbridge was a great company to work with and their product made integrating with the mainframe much easier by turning the CICS screens into web services and the fields into XML.

The mainframe integration with Hostbridge was part of a larger customer data integration project that used Biztalk. Microsoft also did a case study on it. I didn't get any quotes with this one though.
