I can fill in a little more of the technical side of things here. The core challenge is to print a lot of data on an A4 / US Letter sized piece of paper, and then get that data back off the paper and into an application running on a cell phone. Ideally, this would work on any old phone. Realistically, this would be vertically integrated - you'd get to pick the phone, and the printing format for the page containing the data. From the specs and the initial discussions I've had with companies in the field, the speed of light for 2D bar codes is about 3mb per page (Data Matrix) and the choke point is mobile phone camera quality, particularly focal length issues (can't focus properly on the close page.) Approaches: using better phones, deconvolution algorithms, c'mon guys, you know how to fix this. After that, there's some extremely simple large scale database stuff which looks, to my eye at least, to be a natural fit for REST. Basically: Yank data off the page think about it do stuff over GPRS/3G or - ugh - SMS (yeah... SMS out, SMS back... terse data formats.) Done. Nothing about this is difficult. The crypto fits in just to ensure data integrity - make sure that the bar codes haven't been damaged, or that the data on the bar codes isn't stale. Ok? Enough here to be going on with? Do we need to belabor the point further? For the right team, assuming the deal comes through, this would be an easy gig. If it doesn't, there's no gig, no client, no business, even if I disclosed the rest of the pieces here. So it's a potential and there's not much you can do to make it happen or not. But if it does come through, first plausible team might make a pretty good living for a few months and possibly be left with a viable company at the end of it. Can't promise more than that. In terms of IP, there would be full disclosure, no NDAs, no patents on my work as I described. There could be competition, although probably not, and for other reasons I'm not simply posting the whole damn design on the internet (more on that angle later.) Ok, done. Nothing more I can think of to tell you, please ask more questions either here or by email. Vinay
