Hi - A little while ago I posted a question about the implementation of  
a two-dimensional analog of the Kolmogorov-Smirnov test in R[1][2]. As  
there isn't one, as far as I know, people might be interested in a very  
fast C++ implementation called MUAC which is available as a function  
and as a standalone program from  
http://www.acooke.org/jara/muac/index.html. Apparently the code is  
interesting from a computer science viewpoint, and an MPI-powered  
parallel version is available from  

If anyone has any experience of this code, and in particular words of  
warning, I'd love to hear about them (off-list would be best).
