Macfusion — a GUI for MacFUSE

Would it be possible to implement a "stacking" filesystem using MacFuse.framework or the FUSE python bindings?

you'll have to do the work of talking to the low-level C interface in libfuse

MacFUSE.framework is a shim atop the high-level FUSE API

# nontrivial user-space file systems can still be complex, and # their performance/behavior can depend upon numerous factors # besides MacFUSE itself.

A meaningful comparison of clients should incude full understanding of associated servers

Not all FTP servers are equal

MacFusion does connect to FTP servers, but MacFusion is not directly comparable to FTP clients

the moment you mount something on OS X, the operating system can throw a lot at the file system

if the volumesupports "volfs". If it does

it concludes that it must support xattrs

on Tiger, the Finder (the File Manager) refuses to believe that the volume in question can support extended attributes

$ echo foo > ~/Desktop/foo.txt

cmd-i on foo.txt, click on its icon, and paste the icon you just copied

This will cause both the Finder Info and the Resource Fork to be set

Google can and has suspended accounts for the sort of excess activity GmailFS generates. Consequently GmailFS should not be considered reliable for backup purposes. Furthermore, the "Program Policies" prohibit the user to "Reformat or frame any portion of the web pages that are part of the Gmail Service" which is arguably violated by use of GmailFS, which, after all, "reformats" documents transferred via HTTP ("web pages") into data accessible via FUSE.
