The simplest approach would probably be ajax short polling (i.e., an ajax request every n seconds). If the orders page is just an administrative page with a small number of simultaneous users, that's probably fine. If that's not adequate, you could look into comet type solutions. web2py includes a WebSockets implementation in /gluon/contrib/comet_messaging.py ( http://code.google.com/p/web2py/source/browse/gluon/contrib/comet_messaging.py). That doesn't work in all browsers, but it can be adapted to fall back to other methods using Socket.IO -- see http://greg.thehellings.com/2011/04/web2py-websockets-and-socket-io-part-i-basic-display/ .
