I just glanced at the .doc and ran it once last night on my PC -- haven't
looked at the source -- but a possible application of this occurred to me
this morning.  The N files are binary, but it should be easy to restrict
them to ASCII using a command-line switch or a file for PRNG input, right?
Then they would be suitable for Internet (re)mailing.  (Concerns about
cryptographic integrity are irrelevant for my purposes.)

A remailer could receive, say, a 5k message, which might be ~4.5k after
peeling off that remailer's layer of encryption.  XSPLIT could then be
invoked to produce several ASCII files of identical size.  These bogus
files could be mailed to various remailers at the same time as the "real"
file, with a prepended instruction to send 'em to the bit bucket.  Of
course, latency would then have to be added before processing the "real"
file to defeat traffic analyis.  I'm probably missing something, but
it's a thought anyway...
