Can you explain the advantages of PPDD over the mainline kernel 
"cryptoloop" (loopback block device encryption via cryptoapi) ?

I experimented with crypto-loop using blowfish or twofish, and it seems 
quite stable for device-backed loops. Jari Ruusu has raised concerns 
about encryption key re-use with it, so I'm trying loop-aes now...

A short description of how PPDD is different would be interesting!

Thanks!
