The Siteplayer chip has a standard, closed-source, firmware that
implements the IP stack in firmware, only allowing access on two ports -
80 (http) and one other (number I forget, specific to them.)

As such, it can't listen for xAP requests :-(

In principle it might be possible to re-engineer the firmware, but it's
closed source, and the manufacturer has been notoriously resistant to
working with any project / manufacturer who might want to listen on
other ports :-(
