This might be a starting point. this is a function that will parse the links (from the comments on the php site). You should be able to include this into jot someplace before outputting the comments. I will take a look at the Jot class to see if I understand how it works.
<?php
function hyperlink($text) {
// match protocol://address/path/
$text = ereg_replace("[a-zA-Z]+://([.]?[a-zA-Z0-9_/-])*", "<a href=\"\\0\">\\0</a>", $text);
// match www.something
$text = ereg_replace("(^| )(www([.]?[a-zA-Z0-9_/-])*)", "\\1<a href=\"http://\\2\">\\2</a>", $text);
// return $text
return $text;
}
?>
