Be sure to read the info as you install sshfs via homebrew. Getting fuse4x working right requires a couple extra steps.
(I don't want to clutter my laptop with various versions of PHP, Apache, etc. that I need for work, so I run a VM - as of late, I've been using ~/projects/workProject1 as my working folder, mounting it via VirtualBox's shared folders, but the read/write speed on the VM is pretty atrocious. Which is sometimes great for testing, but not so great when I accidentally type "git status" in the VM instead of the host machine, and wait a full minute before realizing my mistake.)
I just followed the homebrew directions, I don't remember doing anything funky to get it installed.
