I've talked about Sharing a Test Environment Configuration in RAD. Here's another idea to try.
Check out Exporting a server configuration and Importing a server configuration. I believe you can use these steps to copy a config from one machine's server to another.
This approach is probably better than using OS commands to copy the files in the profile directory. Those files may contain machine-specific values, like the machine's IP address. Export and import should filter out those specifics.
wsadmin scripts are probably still the best approach, because ultimately you'll need those for deploying your app in test and production. But the export and import approach is simpler in the short run.
