Another reason is, that you only need one machine, where dumps of all supported architectures are stored and where the debugging is done. All people who want to debug dumps just logon to that system. This is especially useful for bigger service organizations, which support different platforms. A third reason is that some people want to work offline. Therefore they just copy the dump to their notebooks. Michael
