My colleagues here at the "Fiji is just imageJ" project have a SIFT  
implementation as a plugin already....
as its aimed at academic use with few people interested in driving  
commercial products from imageJ... seems we are not in patent danger...

There is also another option:
see
  SURF plugin: http://labun.com/imagej-surf/

SURF is very similar to SIFT, as it also tries to derive scale-invariant
features from unprocessed image data, yet it is not patented.

In some experiments, we saw that results of SIFT and SURF
are subtly different, though.

maybe  VTK can implement SURF, but not SIFT
(or for that matter, MOPS, which appears to be patented, too).
