Thanks for your thoughtful comments. crashutah is right that some information will have to be written to the database. I think it would as simple as adding a column to the table already created by the plugin, something like is_opt_out. Any information about legal stuff would be really helpful as I go forth.

I just checked in version 0.4.1, which should fix both the other-peoples-profile problem and the WP single problems that Anton mentions.
