Partial least squares-discriminant analysis

It would be totally killer if mothur could perform Partial least squares-discriminant analysis to identify the most relevant species contributing to shifts due to sample variables (treatment).
This may be similar to the metastat command but it looks like it may be more powerful with identifying structural patterns. Below a link to a paper describing it.
Thanks a lot!
