So lets say i have 2 swfs, one of which is the primary site (A), 1 of which is only triggered for certain frames (B).

If B is be default set to a height of 1px and 100% width, and it contains nothing more than a LocalConnection listener class, would it be possible to load a child swf that has a height of 250px and have it expand the page vertically?

Also with that in mind, if that first part is feasable, would it then be possible to get the dimensions of the child swf that is being loaded, and send them via javascript to toggle a div container to display to the childs height?

Any other suggestions on best methods to approach a scenario like this?
