May 7-11 is the Open Grid Forum meeting in Manchester (OGF 20). I can't be there myself, as I was already in Europe this week (speaking at the very nice 1st German eScience Conference--more about that later). However, many colleagues from around the world will be there.
In particular, the Globus team will be participating in a broad set of session. There'll be a session in the Software Forum track on Tuesday, 2pm, which will include a discussion of what's new in the core software, and more in depth information about GridWay, the latest Globus project, and OGSA-DAI's upcoming 3.0 release. There will also be some "meet the developer" times in the Exhibit Hall, so you can chat with Globus developers informally. Additional information on Globus at OGF is available online. Or, you can contact Jennifer Schopf.
