I tried to contact the ftape maintainer, and was told that he did not have the
time to maintain it, and it was pretty much a dead project.
Further communications went unanswered.
Given the state of the website he pointed me to, I'd say this project is
definitely a canidate for "orphan" status.
I cleaned up the docs a bit, and included a reference to it's orphan status.

After tracking down the original author of the ftape sources, I found out
that he no longer had interest in maintaining it. Apply against 2.6.9.
Purpose: Update status of ftape project in MAINTAINERS.

This file describes some issues involved when using the "ftape"
-floppy tape device driver that comes with the Linux kernel. This
-document deals with ftape-3.04 and later. Please read the section
-"Changes" for the most striking differences between version 3.04 and
-2.08; the latter was the version of ftape delivered with the kernel
-until kernel version 2.0.30 and 2.1.57. ftape-3.x developed as the
-re-unification of ftape-2.x and zftape. zftape was developed in
-parallel with the stock ftape-2.x driver sharing the same hardware
-support but providing an enhanced file system interface. zftape also
-provided user transparent block-wise on-the-fly compression (regard it
-as a feature or bug of zftape).

2. I/O Block Size

zftape (the file system interface of ftape-3.x) denies write access
