re: single shell/ftp user with access to multiple web sites?
Agreed that root sftp/scp login isn't the way to go. Could create an admin-user shell account and then symlink the different hosts, but file permissions would need to be carefully managed by that user. I think unlikely a client who needs the web control panel in the first place would want to be bothered with that path. In the end I think the trouble is likely more than its worth and I'll probably not pursue further.
