as openssh seems not to be fixing it (and i do not consider a 2mb fixed
buffer to be fixed, especially not from a 100mb link here in tokyo and
servers in the states, europe, and africa), perhaps i could convince
freebsd net folk to do so?
FYI - HPN is already a build option in the openssh-portable port.
I do think we should strongly consider adding the rest of it to the base.

There seem to be a couple of issues:
1) Connection aborts during interactive use. I started using this patch
only yesterday but already a couple of times my interactive session to a
machine has aborted from typing one character to the next. It doesnt
seem to be affecting non-interactive use. I have not investigated this yet.
2) -c none handling is a bit weird. There is no way to shut up the
warnings on non-interactive connections ("WARNING: ENABLED NONE CIPHER";
yes, I know, because I WROTE THAT SCRIPT :). Also it doesn't fall back
gracefully if the other side doesn't support -c none; it just aborts the
collection. This means you can't automatically interoperate with a
non-HPN server if you want to use 'none' encryption. This is not
related to the buffer handling but it is part of the same patch set. I
really like the idea of -c none, but I think they have gone overboard
with the paranoia.
