I don't know if this is a relevant thing to present here, but I am 
anyway.  Wasn't there talk about a Mac FS port to NetBSD a while back?  I 
don't remember.  This may be of some use to anybody with lots of free 
time.  It's an interesting project that I'd like to help out with...

MacFS: A Portable Macintosh Filesystem

Copyright (c) 1996 by Peter A. Dinda, George C. Necula, and Morgan Price 

Many moons ago, George C. Necula, Morgan Price, and I built a Macintosh
Hierarchical File System implementation with an eye towards portability. For a
variety of reasons, mostly time constraints and because none of our respective
research areas encompasses file system design and implementation, MacFS has
been sitting on a shelf until now. We have decided to dust it off and make it
available to the net. We hope that some young hackers with more time on their
hands than we have will port it to Linux, FreeBSD, NetBSD, OS/2, NT, etc.

MacFS is a complete (read/write) file system library which can be used to
build user-level and kernel-level support for Macintosh volumes. Included in
the distribution are user-level utilities (ls/cp/etc), as well as a very alpha
Mach vfs (ie, vnode) built on top of the library. The code has been tested on
PMAX/Mach 3.0 machines and Intel/NetBSD machines.

The source code for MacFS 0.1 and a technical report describing MacFS are
available via the "Programs" icon on the web page: 

   http://www.cs.cmu.edu/afs/cs.cmu.edu/usr/pdinda/html/pdinda.html

The source code is also available by FTP via:

                ftp://ftp.cs.cmu.edu/user/pdinda/

Please read the (very liberal) license agreement available in each of these
locations. Let us know if this code is useful to you. Included below is the
abstract for the tech report:

We have created a Macintosh file system library which is portable to a variety
of operating systems and platforms. It presents a programming interface
sufficient for creating a user level API as well as file system drivers for
operating systems that support them. We implemented and tested such a user
level API and utility programs based on it as well as an experimental Unix
Virtual File System.

We describe the Macintosh Hierarchical File System and our implementation and
note that the design is not well suited to reentrancy and that its complex
data structures can lead to slow implementations in multiprogrammed
environments. Performance measurements show that our implementation is faster
than the native Macintosh implementation at creating, deleting, reading and
writing files with small request sizes, but slower than the Berkeley Fast File
System (FFS.)  However, the native Macintosh implementation can perform large
read and write operations faster that either our implementation or FFS.

[Moderator's Note: The creators of the porting package have indicated that
 the package is not supported. You will also have to do some porting to
 get it to work under OS/2.]
