Consider finding that or something similar and reselling it through the Peachy store.
I agree with this. You might be able to literally make it universally compliant with existing sound cards, but the next day someone in china will make a sound card with a higher SNR than you expect and the day after that someone in the US or EU will make one that has a completely different sampling rate. Just pick a best fit and let the community come up with further hacks and suggestions like this USB card or minor tweaks to the circuitry if it doesn't interface perfectly with their particular sound card.
