other web hosting

Hi I noticed that the last update of muse has a way to work with uploading a muse file to another 3 party host like godady.com now. very cool. but from the video it showed u just log into the account and upload by ftp right. well does the files have to be exported as html or can it be a muse file? and then does the designer have to have a godady.com account to do this? or am miss understanding the muse video. i found the video in the new features of muse.  thanks.
