Bulk importing "_users" & "_usermeta"

Does anyone know of a way (plugin) of: bulk importing _users & _usermeta i.e. users, email, password + address1, address2, city, state etc. into a WordPress system, please.

So far I have been able to bulk add basic user information with dagondesign.com’s https://www.dagondesign.com/articles/import-users-plugin-for-wordpress/

But this plugin will only import the core WordPress user data (out of the box) a great solution that has gotten me far but what I need is to import _usermeta also.

Any help will be greatly appreciated!

My plan now is to import the users with dagondesign’s importer then extract the userids/data to manipulate offline in filemaker for a reimport back into the _usermeta table. The latter worries me as I predict there are nonce keys and other stuff that will be hard if not impossible to implement in filemaker.
