I've used this feature a few times and while it works great, here are a few tips:

-wifi has to be enabled in the config for the remote. if you don't enable wifi, the remote won't know how to jump onto the client's home network.
-You can't just send a brand new un-programmed S70 to the client. The remote has to be configured in person the first time (so that you can put in the proper wifi settings).

The thing i love about the feature is that Nevo sends you an email the instant your client executes this successfully.
