What that means is that they will provide a OTA firmware update file via Z-stick, and to other systems that support OTA firmware like homeseer.
While Vera has advertised they have this capability in the past (or could have this feature), they have never actually done it and folks have asked if they would do the HS100 Dimmer OTA firmware update and they said no. So I would not keep your hopes up, that Vera would provide this.
Hubs that support OTA -
Homeseer (you can use the free trial but you still need a z-stick or other z-wave USB dongle), allows you to locally provide the file I believe.
Z-Stick again I think this is locally controlled (you can provide the file)
Wink but it is server side controlled so who knows when they might provide it after getting it from Aeon, they will do it automatically if they have it and pair a device.
SmartThings doesn't support OTA Yet
