Ham Radio request

Is there by any chance someone out there thinking like me and working to develop a magic radio box?

SDR (Software Defined Radios, RX and TXRX) are mostly designed to connect to a computer, using a USB connection for control and one (RX) or two (TXRX) stereo audio signals.

But what I want to do is to put an SDR in my loft, along with auto ATU and loft aerial. Then I want to control it over WiFi from my MacBook. So I need some sort of box (or complete SDR design) that can communicate with the SDR software (I use DL2SDR's DSP Radio software) for both control and audio channels. Something like this



I have in mind to use a good auto tune SDR/ATU, like perhaps the Flex-1500?
