For those of you who have been using MacFUSE, MacFUSE is pretty much dead now. The original author decided to devote time to another project, and refused to surrender the Google Code page to the other developers and open source community so that the project could continue in his absence, so it forked and became Fuse4x:
Fuse4X - The Easiest and Fastest Way to Create File Systems for Mac OS X
Fuse4x works under 64 bit kernels in a thread safe manner (you prior needed to install an unsupported build for this), and the devs are working on Lion support and other stuff.
The whole FUSE thing is such a great project for mounting and reading/writing to file systems of various formats including NTFS, SSH, FTP, Amazon S3, etc. (here's a longer listing:
SourceForge.net: FileSystems - fuse). I believe that MacFUSE is installed alongside VMWare Fusion as well?
At any rate, it is great that this project is not dying, because it is very useful.
For those of you using Macfusion I've written to the author to find out what his/her plans are. In the meantime, if you want to mount SSH volumes you can do so with the sshfs binary included in Fuse4x. You can keep MacFUSE installed alongside, the two play fine together.
