Dokan sshfs for windows:
http://dokan-dev.net/en/download/
This version may be easier to install: http://code.google.com/p/win-sshfs/
You might need to install sftpd on your kindle too...
WARNING: Beware that deleing a symlink from windows using SSHFS will delete the file or folder that the symlink points to! Be very careful with sshfs. It might be a bit safer to use WinSCP instead.
