I saw this article that one can fax with a mobile phone via bluetooth in 10.4: http://support.apple.com/kb/TA22982?viewlocale=en_US Pretty cool, except I have 10.5 and the directions don't work in 10.5. (There's no "advanced" selection when you option-click "More Printers".) I do see that 10.5 has a utility to add a bluetooth fax, which I went through, but couldn't get to work. (At no point did it ask to connect with my bluetooth phone.) Anybody know how to get this to work? Sure would be a great feature when on the road!
