I once played around with the idea of setting up qemu instances of many platforms * many OSes for building binaries, automating as much as possible with qemu's telnet monitor console / ssh in the OS install. Full system virtualization is not as good as doing it on bare metal, but better than cross-compiling everything from one parent OS.
Once set it, it could be a beautiful thing - a great way to show off Nim's portability. It could automatically generate download pages for Nim binaries (and anything written in Nim), where the user selects platform / OS / version from drop-down select-boxes (with [User-Agent](https://en.wikipedia.org/wiki/User_agent#Use_in_HTTP) detection of common combinations). Unfortunately I don't have the funds to do this "in the cloud"...
