Cute.  Worked fine using my android phone aimed at my laptop screen.  I
suppose now I'll be needing a desktop app (maybe part of the screenshot
system) that recognizes QR codes in photos and videos displayed on my
desktop.   :-)

I don't personally know anything about QR codes, and this is the first
I've heard of a need for standardization, but as a W3C staff member, my
ears perked up there.  Yes, this looks like it might well be a good fit
for W3C.  It could be an incubator, like you suggest, or, if it's pretty
clear what a solution looks like, it could be a Submission and then a
Working Group.

Again, I don't know anything about QR codes, but I'm a bit surprised the
folks who defined them haven't tackled this problem.  Perhaps this needs
a new mix of URI and QR expertise.
