Excellent work!  Having a secure, small, low-cost hardware token is an
excellent defense against keystroke loggers, etc.

What are the key size limitations?  Does it work with subkeys?

Can you please e-mail me the diff's or just zip up the whole project?  I
would like to incorporate your changes into the next Nullify release.  I
hope that this will make it into the next official release but that never
stopped me before.

I still do not understand the opposition to the IDEA DLL.  If someone does
not want it, all they have to do is delete it.  Perhaps in the future I
will try and make the installer have an option on whether to install the
DLL or not.
