Something,many of us were waiting for a long time:macfuse
I am quoting original site:
MacFUSE implements a mechanism that makes it possible to implement a fully functional file system in a user-space program on Mac OS X. It aims to be API-compliant with the FUSE (Filesystem in USErspace) mechanism that originated on Linux. Therefore,many existing FUSE file systems become readily usable on Mac OS X. The core of MacFUSE is in a dynamically loadable kernel extension. Moreover,the FUSE user-space library needs a few minor changes to work on Mac OS X.
Currently,the only implemented filesystem is sshfs
After installing,you should issue the following command in terminal to mount some remote system:mkdir ~/test_mountsshfs login@remote.computer.com:/remote/path ~/test_mount
