-c none option

[Mark Eyman]

We are using openssh with backup software to transport data back and
force between clients and backup server. Common sense and some testing
suggest that the data transfer rate is significantly slower when the ssh
native encryption is used. For the backup applications it's probably OK
to use ssh without encryption. Unfortunately, it looks like the recent
versions including 3.0.2p1 do not support the "-c none" option. Is there
a patch or at least plans to fix this?

Also, assuming -c none works, how the password authentication suppose to
be implemented? Encrypted or unencrypted?

Thanks
