I think I'd have to define it a bit better first. :-)  Later tonight
maybe.

Well, Niels suggested 5000-10000 lines.  That's "big" by my definition,
and I do think that it was reasonable to point out that at that size,
it'd be larger than an entire v1 implementation; that implementation
was already too damned big for an embedded system, as far as I was
concerned.

Anyone got a line count for the sftp client and server in the ssh.com
code?  I'd look myself, but for various reasons I don't read through
that codebase, just the specifications.

You can't get much simpler than "rcp", and it works.  It's a shame
that the traditional BSD "rcmd" semantics don't patch stderr,
which forces you to ship a whole separate "scp" command instead
of just using your system rcp (the wire protocol is the same).
