Streaming Worldspace radio content over wireless network

[onyxgaze]

I have a WOrldspace Satellite radio from which I would like to stream audio content to my hi-fi system over a wireless network.

What would be the best way of doing this?

A few options come to mind:
1. If I use a RCA to USB convertor and connect the audio signal from the Worldspace radio to a PC/ Mac running Squeezecenter, can I stream this content over to Squeezebox receivers which are connected to my hi-fi system?

2. Just ran out of ideas..

Any suggestions are more than welcome.

Thanks in advance.
