processing on mobiles would be really cool, but probably too ambitious
for a GSoC project. we can always do that after the project has
completed :-)

wouldn't SIFT (or variants thereof) work really well against a
database of exemplars, i.e: pictures of existing street signs,
isolated letters from the font used for street signage?

i'm happy to advise on this project, but i have to state up-front that
i don't have the experience that stefan has with SIFT, etc...
