I do exactly that... dd piped through gzip then push through an SSH
session to a remote where it's extracted and written on the fly to
another LV.  I use it to move kvm LVs from machine to machine.  Works
great, but there's not much error checking.  If it's critical I do an
md5sum on the LVs at the end then compare.




Are you using scp to push the image elsewhere?
