Don't piss Steve off, it will come back to haunt you.....

Do you want to do this in a category, or in featured products?

The logic here would be to query the database for the table xcart_products.
In your php file:

$newtons_query = "SELECT * FROM $sql_tbl[products] WHERE forsale = 'H' "; 
$hidden_products = func_query($newtons_query);
//Assign the hidden_products variable (array)
$smarty->assign('hidden_products', $hidden_products);

--Untested

The best way to see what is getting included in your assigned variable is to use webmaster mode, in the variables view of the debug window.
