I've had very good luck with Z-Wave. The big advantage is the protocol has active acknowledgement so it knows that a node got the command and responded. Vera makes a unit which is basically openwrt + a webui bridged to zwave; It responds to xml/rest/json-y things. The drawback is zwave isn't cheap. The larger vera unit (not the lite) has a USB port and you can plug in other RF modules - I've seen one for insteon (tho I can't get mine to work), and I've seen them for other shade control units, etc. -m --
