Freeway not only features built-in FTP upload, you can also upload to your MobileMe iDisk. This will upload your site to your iDisk/Web/Sites/ folder by default. You will then be able to view your site on either your http://web.me.com/membername/ or your personal domain, if that has been configured in your MobileMe settings.
Steps for uploading to MobileMe
When you are ready to upload your site open the Upload dialog from the File menu
Choose MobileMe from the Upload pulldown
If you have your MobileMe credentials stored in your System Preferences, Freeway will attempt to access the Keychain utility, click Allow. Otherwise, enter your MobileMe member name and password into the fields provided
Click Ok to upload
If you want to upload to a different location on your iDisk then click the Select button below Upload To: "Sites" on volume "membername" and select a new location. Note that if you use iDisk synching you will be prompted for your member name and password again
To upload to the old .Mac location (iDisk/Sites/) check the Upload to (old) .Mac web space option.
