I need a WordPress plugin that allows me to enter a list of email contacts, and then add contacts to a post, just like in the way I would add categories or tags. It would almost be like I was CC’ing particular people. It would give me the option of sending the whole post, an excerpt, notes or just a hyperlinked title.

I basically want something that is in between a ping and an email and uses my WP posts as a focal point for organization and social management.

The option to password protect or hide posts unless you are a particular user would be okay too, but I so far haven’t used my blog in that way…
