[opam-devel] Using binaries

I think you'll get into complex binary distribution when you distribute set of libraries which depends on system libraries. When you simply distribute binaries or if everything is statically linked that's much easier and opam should just work today (just need to be careful with architecture constraints). But would be interested to see if someone actually manage to do this properly :p

This seems very simple as you say it, but I had not thought about the fact that OPAM already has the capacities to act as a binary distribution platform -- I somehow thought that there would be an announcement of some new extra features at some point designed for binary distribution.

Would it work to mix a "binary repository" that provides only a subset of the packages, and the official source repository, and would package query solvers have a way to do the right thing there? Or would it be the responsibility of the alternate repository provider to include a source-only fallback for the non-distributed packages? (This would make it harder to have a single repository with binary packages for several architectures.)
