Blog in blog utilizes a category filter to display which blogs will display on a page. You add the shortcode and within the SC brackets is the filter statement.
Blog in Blog works for post, Idea Stream is a custom post that does not show up in Post. This means that the Blog in Blog filter has no impact on Idea Stream's post. How can this be achieved?
Blog in blog link: http://wordpress.org/extend/plugins/blog-in-blog/
example of Blog in Blog's shortcode with embedded filter statement: [blog_in_blog category_slug= 'new-toys' + 'announcements' num=5] This reads, all post which have categories of set to: "hew-toys" and "announcements" display a maximum of five post. Can Idea Stream provide the same kind of function?
