No.  Tried using up[0]+up[1] instead, but that also gives me a constant
number - the first always gives me "58", the second "85", but neither
gives the current challenge.

So - is anybody working on S/Key in OpenSSH?  Is somebody using it on a
non-BSD platform?  If yes, what did you do, which s/key library, which
CPU endianness, ...?

Is anybody interested in getting this to work?  I think a portable way to
do OTPs is very important.
