I want to make sure normal ssh usage works, and consider the 
snappy shell to be a bonus.  Locking out normal ssh functions 
seems likely to make users angry.

I like the idea of letting packages define a management command 
which can be accessed in a standard manner.  The apps already 
define a 'start' method; why not add a 'manage' or 
'interactive-configure' method too?  (or is this covered by 
'snappy config' ?)

  ssh snaphost snappy manage myapp

But no matter how slick we make it people will still need to dive 
in deep to investigate issues, so it should allow 'ssh snaphost 
bash' for exploration and debugging.  And scp/sftp/rsync and 
other ssh-based functions should "just work".
