Yep, it's excessive export paranoia. The specs for the crypto i-button
are up on the web -- www.ibutton.com/crypto.html. I'm not sure exactly
what got blown away in the java version -- to be honest, I've not
actually touched the java ones yet.
I think part of it may be a question of what software is available. I
should look into this more.

I believe I was told a developer could potentially get them in 98Q4, and
that they'd ship in quantity starting in 1999.

If anyone else is interested in a button hacker group, send me mail and
I'll put you on a button-specific mailing list.

If only there were a simple way to graft an LED and microswitch onto them
to enter a PIN and reveal internal state without trusting the local
computer... Sounds like a fun hardware hacking project.
Another cool project would be porting IBM CCA or the ncipher API to
an ibutton array...imagine, $1200 for 300 RSA 1024-bit signs/second,
same performance as a $20k ncipher, with a *higher* level of hardware
security.
