[wp-hackers] store all revisions of user metadata in wordpress - possible?

[Jamie Currie]

The usermeta table only gives you two fields to work with -- meta_key 
and meta_value. So you're not going to be able to do what you want using 
that -- how would you know which is the current version of the 
meta_value? There isn't any way to say that one of them is the most 
recent.

The update_user_meta function simply calls update_metadata 
(wp-includes/meta.php -- line 387) which has several action calls you 
could hook into. That way you could simply add your own table and update 
it each time the user_meta is updated, then pull your historical records 
from there.
