Using PHP and cURL, it is pretty easy to get the status of a specific user. Once you have it, what about displaying it on your blog, like I do in WPRecipes footer?

function get_status($twitter_id, $hyperlinks = true) {
    $c = curl_init();
    curl_setopt($c, CURLOPT_URL, "$twitter_id.xml?count=1");
    curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
    $src = curl_exec($c);
    preg_match('/<text>(.*)<\/text>/', $src, $m);
    $status = htmlentities($m[1]);
    if( $hyperlinks ) $status = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]", '<a href="%5C%22%5C%5C0%5C%22">\</a>', $status);

The function is extremely easy to use:

echo get_status('catswhocode');
