Execute non-native executables directly by passing them to an instruction set emulator at execve() time.

For more information, please see: NetBSD ∘ (NetBSD ∘ Toaster) / jkoshy.net.

This is not an easy project. It touches upon:

• Linking and loading,
• Instruction set architectures,
• Binary emulation,
• POSIX compatibility,
• and others.

It also has a small kernel component involving changes to the execve() path.

Primary milestones:

• (Proof of concept) Invoke qemu in its 'User-Mode Emulation' mode on a non-native binary.
