Thinking of a reason is the hard part of this suggestion.
Thinking of a reason that couldn't be accomplished with a simple file transfer is even harder.

Question:
What use-case would require that the originating device **not** create a file?

Ans:
Both devices (the Kindle's flash and the other device's something) using semipermanent memory.
Say, maybe flash or SSD drives.
PLUS:
The Kindle is physically secure and the other device is not physically secure.

Then you would not want to write (or print spool) the output of a program to the storage memory of the un-secure device.

Because it could be physically stolen, the memory chip(s) removed, peeled, the micro-controller hacked, and the erase blocks not in use read.
(A really big technical challenge, but a serious concern among manufacturers and users of big SSD drives.)

Hmm...
Still pretty far out -
And I still don't see why this use-case could not be answered by running a TrueCrypt (or the ms equivalent) storage partition on the originating device, and writing a file to it for later transfer to the Kindle.

No one ever asked for a secure storage facility on their Kindle that I can recall.
So we (twobob and I) never did try creating a LUKS partition (or a file-as-a-device) on the Kindle.
(We did discuss it, as part of a non-public project.)
But I am pretty sure that the kernel version(s) used in any of the touch screen Kindles is new enough to support it.

Perhaps this suggestion was just to answer the technical challange and does not have a (practical) use-case.
