PHP implements href rewriting in the final stage of output. You could
easily hook in here using output buffering.
ob_start('weblogize_links');
function weblogize_links($buffer)
{
// parse the output $buffer and modify all links
}
A special gotcha may come in here: take care to only rewrite links that
point to your own site.
