ssh isn't too widely supported (from programming language libraries).
Does libssh2 even support scp?

WebDAV is possible, but it comes down to how much crap it will depend
upon, all of which needs to go into the appliance.

FTP is widely supported and well understood, and the servers are old,
small, self-contained code.  I really think it's better for this, and
not just because I once wrote an FTP server ...
