You can do that already.

Simple capability management: pass capability_type.

Advanced capability management: pass capabilities, an array of capabilities
keyed (exactly how you described it) with edit_post, edit_posts,
edit_others_posts, delete_post, publish_posts, read_post,
read_private_posts. See get_post_type_capabilities() and
register_post_type(), both in wp-includes/post.php.

Note that the meta capabilities have no special mapping/handling that
(edit|delete|read)_post have, when capability_type != post. That will likely
come as an option in 3.1, but you can add that through a filter on
map_meta_cap if you are so inclined.
