Just trying to get this code working - can someone help me get zero-confirmations notifications working? I'm not sure if I'm missing something obvious or if the instructions / code are missing from Github.

I'm seeing a monitor script, "bpn/monitor/unconfirmed-monitor.php", looking at a table called active_uncomfirmed_monitors. This seems to get populated by a script called "bpn/www/tx.php", which expects a load of json_encoded Bitcoin transactions, presumably unconfirmed ones.

But what's supposed to be hitting tx.php, and where's it getting its transaction information from?
