It just occurred to me that, because the Peachy Printer's only input/output is through a sound card, it should be possible to control it entirely from a website. (And maybe even a mobile one, though I don't know if the proper APIs are implemented yet in phone/tablet browsers.)

Would anyone else like 3D model gallery with a big 'print' button right on the page?

As soon as enough details come out (I'm not a Peachy beta tester), I'll start trying to make this happen. A further idea: combine this with an in-browser editor. It would be 3D design and printing with no software installation!
