There is an open source reimplementation (or two?) I thought I used this one: https://github.com/xaberus/vscode-remote-oss https://github.com/xaberus/vscode-remote-oss and everything just worked, though the directions on that page look complicated, so it might be the wrong project. It was in the store that ships with the open source build and was definitely open source.
