Cloud manage a Netgear WG102/103 and so on?

Hello,

this sounds to be cool stuff: Tanaza. I tried to cloud manage an old wg102 with the free account they provide.
It seems they also support other Netgear models (and also of other brands).

I cannot understand how it works. ANy one has an idea?
For me it's amazing the possibility to upgrade a device and cloud manage it. Not clear the architecture though.

But I find interesting the possibility to use it to take control of my family aps...
