Good:
* Temporary credentials, that can be added e.g. per machine basis (very useful!)
* Very simple Dropbox integration
Bad:
* No way to upload to a subdirectory (but in dropbox root), it should be really like other Dropbox apps, that goes to a separate Apps/ dir.
* No way to separate uploads into directories either, eg. `scp filename user@host:somewhere/` will actually create a "somewhere" file, instead of "filename". `scp filename user@host:somewhere/filename` will upload nothing.
Ugly:
* I'm logged in as "Signed in as michael.lawson", not sure what is going on, account info leaking across accounts, or it's just a placeholder text set up left over from somewhere?
* Using `ssh-dss` server host key, have to explicitly enable in my ssh settings with HostKeyAlgorithms (see http://www.openssh.com/legacy.html)
* Password authentication with SSH, so either run it interactively, or use `sshpass` to do upload in a script non-interactively.
