As introduced in #176 by @tcr3dr:
At this point I'm comfortable floating dronekit-sitl-runner as a cross-platform alternative to the Vagrant sections.
This uses precompiled binaries on S3 that are generated in a separate CI step: https://github.com/tcr3dr/dronekit-sitl-builder Three versions (3.2, 3.3-rc5, and 3.4-dev) are supported and built for Windows, OS X, and Linux.
Basically, we should just outline what assurances are needed from that tool to use as a replacement for the Vagrant install (which I assume is less desirable in all circumstances).
