Matt and Jing, I just visited the website of the GlobusWorld 2004 which is in San Francisco right now. I noticed that there is a talk about XIO (http://www.globusworld.com/program/developer.asp). If Globus already has or is going to release XIO soon, we probably need to re-consider our design for 'GET FILE' based on this technology. Sincerely, Bing
