KO,. For now one comment. I rely quite heavily of moving files from my laptop to the pii's using ftp. I cannot ftp to the machine (I believe). I have ssh but no scp in the free ware package. I will be happy to entertain other methods of doing this, so far we have accepted incoming ftp from certain domain's only. n general we should ensure that people from the outside (including e.g idas, nbi, tamu) can move small as well as large files effeciently.
