Speaking as someone who doesn't encrypt their desktop but is thinking about it:
you can't share (readable) data over one's home network if the sending PC is disk-encrypted?
For example, are you saying that if I send a video file from my PC, which is disk-encrypted, over LAN to my NAS, then the NAS would not be able to read said file?
Soooo what you're saying is that that hi-lo driver no longer has a job, right?
