Afuse is a useful utility to allow one to automount filesystems using FUSE. Below is a nifty hack shown to me by Jeremy Kerr to automount directories on remote machines using sshfs:
sudo apt-get install sshfs afuse
afuse -o mount_template="sshfs %r:/ %m" \
-o unmount_template="fusermount -u -z %m" ~/sshfs/
Ben Martin has documented afuse and some useful examples here.
