RFC: Snappy shell

[Zygmunt Krynicki]

Hey

So we can keep normal shell on port 22 and use ssh subsystems (like
sftp) to install a snappy-cli subsystem. Why? Then you can have a
Ubuntu command that ssh's into snappy cli. One port, many features. So
far I only know of sftp using this but the mechanism is generic.

Best regards
ZK
