Sounds great! I would be very interested in such solution but rather windows or Linux based

I have worked out a way to achieve this and I wondered if there was sufficient interest for me to write up a guide?

The basic premise is that you run a couple of small applications on a PC connected to the same LAN as the Slingcatcher (one which I wrote over the weekend but which I'm happy to allow people to have for free) and you connect your Slingcatcher to this PC when you want to view the remote Slingbox stream. This PC then takes the incoming connection and does what is necessary to make it communicate with the proxy server instead.

The PC doesn't need to be especially powerful, typically this could be the PC you use as your home media/iTunes server.

In my case I am using a Mac Mini, which means the application I wrote is currently Mac-only, but if there is interest then I'm happy to create a Windows version too.
