Connect to NAS media folder on a different network? ATTENTION WD NERDS!

I currently have a WD TV Live Hub that connects to a buffalo tech. NAS.   If i were to take my WD to a friends house and connect it to their network, is there a way I can have my WD connect to my NAS back home??? 

I have a ton of media on my NAS and it can take forever to move files into the WD.  

I appreciate any and all help.

Thanks 

No, unless you create a VPN connection into your home network that allows network discovery and broadcast passthrough…

I understand creating an OpenVPN connection to my network, but how will the WD connect to it?
