Will I be able to remotely control the rasplex client from an app on my nexus 7 2013? Much the same way as I would with Yatse and XBMC.
Yes, apps like the Plex Client can be used to control RasPlex from Android devices (and iOS, not certain about Windows Phone, but suspect that would work too). Can also control it from Plex/Web.
Ok that's good to hear, thankyou :)
