@ the FutureWell, hacking hardware can be like an arms race - as soon as one side takes a step that's too much for the other, the efforts put into development increase (stakes getting higher...).
One can easily iterate the whole race in advance ... up to a point where it would be similar to pay-tv smartcards and game-consoles... just like music and DRM

In consoles (as reported with the X-box) there's even encryption on the internal high speed busses ... and that didn't help much against all sorts of hacking - it just wasted ressources and (for example) when looking at the X-box 1 that money/time would have been much better invested into thermal design in order to prevent massive damage, rework etc.
Something sImilar happened to the music industry - MASSIVE amounts of money were spent on DRM and lobbying - grandmothers and toddlers got sued ...
... until the industry realized (they are still learning it) that selling massive amounts at more reasonable prices is better than overprotecting and selling at a premium - effectively hindering it from beeing sold *G* (economies of scale).
Nobody can tell how the future will look like - but one thing is sure - there's a demand for better image quality (see digital cameras or your phone (yeah, the pocket camera with SMS and speech-capability... and games... and compass.... and and and ... ).
I'd really like see the whole IR-evolution turn into a volume-direction:
Just imaginge the fun one could have with a hobbyist 120x120 sensor module for sub-150$ ...
... how many Arduinos have been sold yet?

... IMHO it's just a matter of time when somebody smart at marketing (

) realizes the potential
