Is it possible to access PUN from "outside" Unity? (not Answered)

Hi.

I hope someone can help me out here
I am building a system to synchronise multiple GearVR units so videos can be played at the same time. So i build the App in Unity - it worked.

Now my Client want's to have controll over the device-playback from outside of unity. (Inside unity worked great already using PUN on android and a master PC application)

Is it possible to connect via a .net / visual basic application using the Photon SDK to the unity Apps via the same RFC calls?

i am kind of a noob i regards to networking as this is my first project with PUN

Thanks for any advice!
Martin
