Event bus for configuration changes
A common problem in developing Symbiosis functionality is the difficulty in detecting configuration changes. Currently Symbiosis is configured using SFTP, but has no hooks into that system, so it's always going to be somewhat hobbled.
It would be good to have some sort of event bus to detect configuration changes, and act upon them at the time. This removes the need for polling which is wasteful and not very timely in some cases. Using a more event based approach would make configuration changes more or less instant, and maybe more reliable too.
One way of achieving this would be to have hooks into the SFTP subsystem. OpenSSH doesn't seem to have them, others do, ie https://www.npmjs.com/package/ssh
Whilst not advocating the addition of node into the stack, it would be good to have this functionality somehow, so it's open for debate.
