Questions on livecd-iso-to-disk

[Williamson Grant]

Hi all, a couple of questions.

Has anyone created a simple process to turn a livecd/livedvd directly  
to a compressed usb image, i.e. bypassing the need
to have a usb key itself.  Reasoning I am asking, I want to build and  
maintain usb images on a remote server.

Has anyone already implemented full liveusb encryption(not just home)  
with overlay, home. Or is the performance just too slow?

Thanks to all who have worked on these tools.

You can certainly just create an image with dd, losetup it and then use
that instead of an actual usb key.

Encryption of the overlay is ... odd at best.  I guess that it's
probably doable, but the performance and risk of corruption is going to
increase exponentially.
