I am proposing this as a practical solution that can be implemented
effectively mainly on floppies. Hard-drives might have to be dedicated
to stegonagraphy (As Matt points out below).

So it seems. However, I am wary of the possibility that there are
drawbacks to the scheme that I haven't even considered yet. I'm hoping
that other astute readers such as yourself may be able to point them out;
as, practical stegonagraphy may become a necessity in the near future.

My original post only outlined the basic premises. I had not, at that
point, realized that floppy use would be a virtual necessity.
