Impressive! Risky! Cool! :-)

Got it... so you can use the aespipe program anywhere, so it's a good candidate for putting on a rescue CD-ROM.
Can aespipe use alternate encryption ciphers? Since it is statically linked, it seems to be AES-specific.
As always, thanks to Jaari for clarifying these points!
