If you've got a 2+ megapixel camera phone, you can use scanR (
http://www.scanR.com/ for details) to fax it for you...just take the picture, send it to
[email protected] with the phone number you want it faxed to as the subject line.
Or if you can take a picture with a digital camera and transfer it to your laptop, you can send it to
[email protected] the same way via your regular email.
disclaimer - I work for scanR

But I do this myself all the time because we gave up on our fax machine long ago.
