These do look interesting and maybe better than the S/Key 64 bit key.
I remember some bad stories about one of the 'Aladdin' companies
(there are quite a few who use that name for security products).. but
not sure which.

The bigger question is who can we get some 'professional' opinions
from? My crypto math is not good so I could not give an opinion of
whether one usage of AES-128 versus another usage was equivalent,
better, or worse. I would hate for us to end up with any solution that
would end up on Shneier's Snake Oil pages. [I remember one token
device that some people I know evaluated a while back that while it
stored the key encrypted in AES-128 etc.. it had a register where it
stored the unencrypted user token and could be looked at under any OS
other than Windows.]
