SMIL Variables

I am looking for a little SMIL help. I had a question come up that I am not
quite sure how to answer. If anyone knows if this is possible, please let me
know. I don't need to know how at this point, just whether or not it is
possible.
 
I am making buttons on a realvideo clip. I need the ability to read in a
variable to that button so that when I click the button inside of the clip
it goes to a link with the variable as part of the URL. So if I come from
the home page, the variable could be "home" and then when I click that link,
is looks something like http://www....com/file?home
<http://www....com/file?home> 
 
Any help is appreciated!
