The difference between a memory smartcard (or iButton) and Arcot's
system is that the smartcard is less likely to be available for
copying all the time, I can take it out and put it in my pocket.
There's probably no reason why you could not put the Arcot encrypted
certificate on a memory smartcard (or floppy) too.
Anything that does not succumb to an offline attack is of course an
improvement on PGP-style private key rings. Unless their claims are
exagerated their stuff may be useful in cases where using
crypto-smartcards is just too expensive.
