From what you say, perhaps you can use IFrames for this purpose?
what i feel iframe may not serve the need, it can only show the contents but not helpful to user. When a content is already in other webpage why we bother to go on the page that just put as it is on thier. Google will not index such pages. IF they works as like Google news segregating the many things in one than it may be useful and yeah need to link that page also.
