Daniel that is an interesting idea, but I expect it will quite slow given the overhead.

I'm currently building the the LEDE system on the docker image running on my Surface 4, i7, 16GB, Windows 10 Pro 64Bit the build has been running for about 18 hours and still has not completed. The same build on the same machine but running Ubuntu 17 on VMWare Workstation Pro 15, builds in about 2 hours.
