  A few years ago I implemented a version of SFTP on a 4.2 system.  It was,
as the name implies, very straight forward to implement.  One problem with
this protocol is that it requires the sender of a file to know the exact
length of the file before sending.  This means that some "in-line" conversions
on the data are not going to work.  For example, sending a file in ASCII
mode requires that the local end of line is converted to the CR-LF pair.
To send a file in this mode required two passes through the file, one to
determine the size and one to actually send it.
