sudo chmod a+rx /usr/local/bin/sshfs

sshfs user@host:folder local_mount_point
and you'll be able to access the contents of "folder" on the "host" in the local folder named "local_mount_point" (of course, you can name it as you please). Hence, a simple
Of course, you need to install the software only once, and then you can connect (mount) as meny times you want!
BTW, TextWrangler allows to do this without installing extra software (it can save/open files via ssh on remote hosts natively).
