i have done a script that can export users, groups, group types, relationships and sitemap info, but you will have to use xotcl (=object oriented tcl, needs a module to run in aolserver) if you want to use it. the "cloning-package" as i call it can be found here. if you use it and have problems let me know, i did develop it for 4.5 and did not try it with the head version.
