Will SOA collapse under its own weight?

In a previous blogentry, I mentioned the so-called XML performance crisis that may bring down SOA and Web services networks in the near future. Colin Adam (of Webservices.Org) and I recently had a talk with Cory Isaacson, CEO of Rogue Wave Software, who provided another take on this impending performance crisis. Isaacson says XML messages used to be 1KB, 5KBs, or 10KBs in size. Now he sees messages of 100KBs, 500KBs, even up to 50 MBs. He gives our current infrastructure about 12 months before networks start to choke on bloated Web services messages. His comments, along with a potential solution that he is putting forth, can be found here.
