As a user of hpn-ssh for years, I have to wonder if there is any
reason (aside from the sheer cussedness for which Theo is infamous)
that the window improvements at least from hpn-ssh haven't been
backported into mainline openssh? I suppose there might be
portability concerns with the multithreaded ciphers, and there's
certainly a good argument for not supporting NONE as a cipher type out
of the box without a recompile, but there's not much excuse for the
fixed size tiny buffers - I mean, it's 2008 already...
