Of course, I always recommend upgrading the applications with the feature 
and contributing the patch... but, assuming that is somehow impossible.

You might be able to do something similar to libtrash[1].  Libtrash gets 
preloaded for the application, and overwrites the remove function calls in 
glibc so that a trash can is implemented.  Basically all deletes become 
moves to the trash folder.  In the same way, you could make all deletes 
shred the files.

Disclaimer: preloading is a nasty hack.  Many people discourage it, and 
they're all right.  But, it may also solve all your problems :)
