Remote control of audiostream via Iphone


I just installed Tversity to stream audio from my PC to my Philips Streamium WIFI audio receivers; this is working fine.
I also have an app on my Iphone to remotely control Itunes on my PC.

Is there someway to link both, so I can remotely control (from my Iphone) the audio being sent to my Philips Streamium units?

Thanks in advance for your help.
