Unfortunately, Dreamweaver MX doesn't include support for SFTP. For people like myself, that poses a problem for the development environments I work in. To get around this, there is a program called Tunnelier by Bitvise. It installs fine under CrossOver Office 3.01+. It includes an option known as FTP-to-SFTP Bridege that works great. This is the only work around I know of so far.
