While Ron was visiting Australia in August, he spent a day chatting - on video - with the Commonwealth Bank's CommSee architecture team.  I'm pleased to report that these conversations are now available online at SkyScrapr as an ARCast.  It's well worth a look if you are interested in the design and architecture of CommSee; there's lots of in-depth discussion regarding CommSee's design drivers, as well as how they approached developing a pragmatic SOA within the bank for this project.  Compelling viewing if you ever wondered how you'd design a smart client/SOA application that could serve tens of thousands of concurrent users :)
