It does not have to be just one map... Freshmeat.net and some other
sites use something called Trove categories (e.g. 
There can be several trees in which a package can be found, possibly even
at different leaves in the same tree.

Example trees for R could based on general method or data type, or whatever.
A tree could be based on chapters in some standard encyclopedia, for example.
We could develop several trees, each one aiming at a specific discipline: one 
for chemometrics, one for sociometrics, econometrics etc...

A paradigma in webdesign is that each webpage should be accessible within at 
most three click, otherwise it will not be read... the same holds for these 
kind of search trees (compare for example with descision trees, where the 
depth is rather irrelevant)...

If adding more trees make packages more used, we gain something...
