Is n-Stream working with homeplugs an issue?

Hello folks,

I am just about to set up a homeplug network but it's occurred to me that there might be an issue with n-Stream.

The homeplug network plugs into the same router that provides the wi-fi that the system currently runs on but I understand that the homeplugs set up their own private network. If this is the case, how would n-Stream communicate with my ND5 XS? The iPad would be on the normal wi-fi network and the ND5 XS would be on the homeplugs private network. Is this an issue does anybody know?

Thanks for your help.
