It took me forever to find a decent and free (I know… ) webdav hosting service to sync Omnifocus between my mac at home, at work and my iPhone. I really didn’t want to pay for .mac since I’ve had it before and used almost none of it. Finally I found one that seems to be doing the trick and offers much more than enough space for the job (2gb) -myDisk. Took about two and a half minutes to set up. Nice.
