An encrypting target would be nice, but does it offer any value over an encrypting loopback device?
(I assume LVM2 is compatible with the existing loopback encrypting devices.)
A compressing target would be uniquely valuable because I don't think it can be implemented via a loopback device.
i.e. I believe a loopback device requires a 1:1 (or constant) ratio between input size and output size.
Actually, that sounds like a pretty interesting problem to try to work on.
