Thanks for all the helpful posts.
I think I will go with just using my Linux laptop for it. I can just encrypt
the swap, it's not difficult, I've played with cryptoloop before. I didn't
use it for swap, but it's identical. And while I'm at it, I'll ju

There has been a lot of discussion in the past about VirtualLock. First
it seemed to be a viable solution,
Swap is indeed optional.
I've been running Debian with X/e16/screen/vim/irssi/xmms/mozilla for
a a while (a year? or two?) and never noticed any performance
difference. I doubt anyone else would either.
(DDR2-800 2048MB, 2GHz dual core Athlon, before that DDR-400 1024MB,
2GHz single core Athlon).

I just realized something. You have the option to NOT use swap
space in Linux. Does this mean that there is no memory written
to disk? If so, then it might

Since you are only encrypting in place and not transferring the

public-key encryption. Any tool that
