The limitations of QR codes, if we embed a URL, should be plenty, even
without any compression, eg:

http://osm.org/qr/21d906f1-7a93-49f5-beee-7c126b840a85

Although the QR code could be smaller if less error correction was
used, or smaller pixels, or we could make them bigger and have the OSM
URL underneath...
