data base for every package? I will support such an effort, but mainly
as a application for the algorithm. The data base will start from all
the packages mentioned in lfs project and grow from there.

How do we treat versions? we can only list the latest version, but
someone may prefer certain versions (gcc2 for kernel?). We can list
only the url root, but different versions sometime reside in different
directory.

I am thinking list url in two parts, one is the common path including
package file name, another is a mirror list. A lot of packages may
share a common mirror list. I suspect there is a simple algorithm can
be used to choose the optimum mirror. I live in Maryland, United
States, but I often find mirrors in Europe response much faster than
mirrors in here.
