Lightbulb Group Buy for 5.1 Channel PCB's for Computer Surround Sound

I was wondering if there is some interest in doing a group buy for PCB's and possibly components for a 5.1 surround sound amp for a computer surround sound system.

The system would take analog inputs from the computer sound card on 6 channels (optionally 4 channels) and amplify each channel. There would be one power supply for the amp.

I was thinking that this would be a good project to utilize the National LM3886 or LM4780 as well as the LM4651/ 4652 subwoofer amp set.

One board would reduce costs considerably over having seperate boards for each channel or stereo pair as well as the subwoofer.

I was thinking that this would be a good project since many people would like surround sound on their computers for games, videos, music, etc.

Post your thoughts and interest here.

I could take the lead on organizing and purchasing, but would need some input on the engineering aspects.

I would be interested if it could take a toslink or spdif input...

For the sake of costs and component count I would suggest using dual amp chips...

x2. Digital inputs would be nice. How much are these boards gonna cost? I was thinking about building a 5.1 channel system using Brian's PCBs, but if a 5.1 board could be made, I would be in.
