Hello,

About 4 weeks ago i released an application (application for ecology) capable to do this. It implements an ImageJ version
and the statistical tool R. In R you can use the library spatstat to perform a nearest neighbour analysis,
voronoi, delauney etc.
It is quite fast and i tested it with 100000 particles (nearest neighbour analysis!). I've released also a Flash tutorial how to perform this.
http://www.uni-bielefeld.de/biologie/Oekosystembiologie/bio7app/index.html
Look at-> Flash Tutorials:"Transfer precise values from a particle analysis to R" and "A point pattern example"
Maybe it is also applicable for you problem.
The application is, at the moment, only available for Windows. It uses ImageJ 1.35.
If you need a higher version number:in about one week i will release a new version bundled with an improved version of ImageJ 1.39d.

With kind regards

Marcel
