Someone should do something similar with Gentoo's portage, because the potential of IPFS could lead to amazing things, like verified pre-compiled -march=native builds for every architechture Gentoo supports.
For a while, I have interested in the idea of modifying the NixOS stdenv (standard build environment) to use a compiler that emits LLVM bitcode, and then having a function that takes any derivation to an equivalent derivation containing the result of running the LLVM IR through the specializer for your architecture. This would mean that you can share a binary cache with others, but still get `-march=native` performance. There's also some pretty interesting ideas along these lines wrt. randomly permuting instructions to prevent ROP attacks (you could even implement that as yet another package -> package function, so that you don't have to do the full set of LLVM optimizations for every package at boot time).
