To my untrained eye, this seems an excellent and very general solution.

As a slight but positive side effect, it also seems to open the way to
per-CPU optimized library versions; if you have a 686, you add 686 (or
686-cmov) to /etc/dpkg/legal-archs, and can install either

libssl0.9.6-0.9.6c-2_i386.deb or 

on a x86-64 you'd have the choice between those same two plus 


Of course, that's only the dpkg side of things; in any case, you'd still
need a way to present the extra choices caused by legal-archs in
dselect. How would that be done?
