    168 Yes. Tahoe-LAFS comes with an [source:docs/frontends/FTP-and-SFTP.rst SFTP server]. If you point [http://fuse.sourceforge.net/sshfs.html sshfs] at the SFTP server then you have access to Tahoe-LAFS through FUSE. Alternately, [wiki:pyFilesystem pyfilesystem] interfaces directly with Tahoe-LAFS through the latter's [source:docs/frontends/webapi.rst web-API] and provides both FUSE and Microsoft Windows filesystem access. See #1353 for discussion of possible improvements to FUSE integration.

    170 There could be performance problems with the FUSE interface if the apps that are using the filesystem use it in a way that doesn't fit Tahoe-LAFS's semantics, and the FUSE layer is required to make many copies of entire files in order to emulate the desired semantics. See [http://lists.alioth.debian.org/pipermail/freedombox-discuss/2011-November/003162.html Zooko's post to freedombox-discuss] and [https://plus.google.com/108313527900507320366/posts/ZrgdgLhV3NG Zooko's post to Google+].
     168Yes, but it is not recommended because while it will work for certain usages, its performance will crawl to a halt for other usages. You can try it and see if your particular uses happen to fit into its performance contours.
