Take a look at my comment above about hshell. It has all those things you ask for. Feedback would be useful!

The problem with this space is incentives. HShell exists because it was easy to build given the structure of our main product, and I wanted it for our own internal use. But making it a stable long term product on which anyone can rely requires signing up for long term maintenance, and nobody pays for shells (or do they?). So it's got to be a labor of love.
