You can mount remote filesystems via SSHFS. After that, you can just use Nautilus (the Ubuntu filebrowser) to manage your files on Ponyland.
/vol/bigdata from Ponyland to
~/bigdata on your local computer.
mkdir ~/bigdata sshfs $USERNAME@applejack.science.ru.nl:/vol/bigdata ~/bigdata
You can unmount using
fusermount -u ~/bigdata
