I think Daniel is using raw rsync, without dirvish, for moving
between machines.  That is sensible, given that he is copying
raw data.

However, may I suggest putting a swap cage in the old machine (if
there is a slot available, a big if) or putting an E-SATA card
in the old machine along with a trustworthy SATA to PATA adapter
if necessary?  A direct drive-to-drive copy will be faster than
the network, encrypted or not.

Daniel, Audio Precision is not far from me;  I probably have some
unused swap cages if you want to borrow them for a while.
