I'd be interested in taking the signals meant to write data to a CF 
card and using them to write to two cards in parallel so that I have a 
redundant copy. Making one card faster than the other or delaying the 
clocking slightly would be acceptable. Without having looked into it 
I'd imagine that two structurally identical cards should allow one 
card to be driven "blind" without too much risk of data loss.

Comments ?

The object is to provide data backup for a system which presently 
writes to a single CF card. Occasionally cards fail and if you want to 
avoid this a duplicate copy is essential. The writing system is not 
amenable to modification - the dual media system must be transparent.
