That would be a new way I have never thought about. :) But to me using
the "config" array seems a bit of a "misuse" for this purpose.

I would let USER store the information in cache_hash (see other post
about the API). The problem here is the same as in your approach, the
cached information will only be "refreshed" once the USER object is
recreated. But if this is desired (e.g. not dependent on user session or
page where the plugin is being called from), you could use any cache you
like.
