+1 That's an interesting technique -- thank you for sharing.

Does you recommendation of a plugin mean there's no way in a stock wordpress install to get this granular level of permission control?

@AhmedMahdi Thank you, yes, I meant capabilities (fixed in the post text). The link you provided shows how to programmatically add a capability to a user -- however, it looks like that adds the capability programmatically. I looking for an Admin UI feature that allows you to assign capabilities -- similar to how other systems allow you add individual ACL rules to a user account.
