Daniel messaged me off list asking how I did this, I figured I'd reply here.
There isn't anything magic about this.
I bought the ISY and some aeon labs smart switches.
I setup the ISY on the network and then loaded it with the current alpha firmware (5.0.7).
Then I paired the zwave devices with the ISY and verified control using the ISY admin panel.
From there I created a virtual output in the form of http://user:pa...@xxx.xxx.xxx.xxx
Then I created output connectors with get commands that corresponded to the REST info of the controller.
/rest/nodes/ZW002_1/cmd/DON
/rest/nodes/ZW002_1/cmd/DOF
voila.
I am sure this would be more (much?) complicated if I was trying to use dimmers, use advanced zwave parameters, or query information from zwave devices. But I'm not, I'm just sending on/off commands - and that is (Very) simple.
What remains to be seen is the reliability.
