Right. I wasn't thinking about all the site banner and navigation stuff. What you did should work fine. Probably the best way to go is at the bottom of product.php replace:

func_display("customer/home.tpl",$smarty);

with:

if ($main == 'showstf')
  func_display("customer/main/send_to_friend",$smarty);
else
  func_display("customer/home.tpl",$smarty);
