Summary: Extending the external ram disk idea

I agree that an external ram disk would be a good idea.  To make
it more viable, however, I'd like to see it have multiple modes
of operation:

1) As an external disk replacement (per the original posting)

2) As a "whole disk cache" (if that's not a contradiction in terms)
   that could sit in-between the external disk an the main unit.

The advantage (real or imagined) of the second arrangement would be
that the ram disk could simply swallow-whole a disk that is inserted
in the external drive, without user intervention.  Given a larger
memory, it might be able to first swallow a disk from the external
drive (as a ram disk) and then act as a cache for a different disk
(inserted in the external drive once the first one has been ingested).

Comments, anyone?
