Charlie - Could you post the list of conferences you have in mind? I am aware of: Web Services: From Technology to Reality A Workshop on Modeling, Architectures, Infrastructures and Standards for Business Collaboration March 4 through 7, 2002 West Coast, USA Hosted by the Object Management Group Sponsored by Borland but I'm not aware of the one in London you mentioned. I guess it might make sense for me to present in London (only 2 hours away). With this in mind I'm happy to chip in with Sean (and whoever else) on the generation of a slide set.
