Unload & load swf (with alpha if possible)

He guys,

I’m building a website, which contains text,images/video’s on different pages with the same layout. the index.html(swf) contains only the layout of the website, without any text or info. onload at the index.swf the about page will be displayed with the info and videos in the ‘index layout’.

When I click on a new link, I want to load a new(ex. products) swf INSIDE the index.swf, which always should be onstage. than when I click to another page again, it should unload the products.swf(not the index.swf) and load a new swf (ex. contact). The pages need to change smooth, so it would be nice to unload & load them with an .alpha.

Is this possible, help?
