Guys, I agree that this would be too slow, however the security it buys us is
well
worth the effort. IMHO, this is viable if you don't have a Palm to use SKEY
or
something like it at the time. Besides, with time, you'll get used to it.
It'll be far less painful than having your keystrokes sniffed.
Of course, if they do sniff your keystrokes, they'll know what you type
to your cell mates. :) So it won't matter what the fuck your passphrase is
or how well it is protected. :) It ain't the passphrase they're after, it's
the data on your system, and if you're the one typing it, heh. That's as good
as they need.

A-Yup.

I love the smell of Malathion in the morning, it smells like brain cancer.
