Any bright ideas or plugins to recommend? Wordpress

I need to make a WP MU so only subscribers that is given access can view certain categories and this is to be different subscribers for different categories (or posts)( i mean to be picked up which can for every category or post). For example: -Category 1 can be viewed by: *subscriber 2 *subscriber 6 *subscriber 11 -Category 2 can be viewed by: *subscriber 11 *subscriber 13

Hope you got what I mean. :) Thanks in advance, I'm thinking this for a开发者_C百科 week now but can't put my head around it.
