The 'Disk' option for syncing is for people who are only syncing between Macs (no iPhones) who have a USB drive that they physically carry between computers, or something like that.

Using Bingo as your server, you'd need to choose WebDAV in the sync settings.

Some of the issues described on this forum are specific to certain WebDAV servers that don't follow the same specifications as MobileMe. But some of the issues are true for all 3 syncing options. Many of these issues have been addressed in the latest sneaky peeks for Mac and 1.0.3 for iPhone, but we still have work to do, so if you need something trouble-free, I recommend waiting for OmniFocus 1.1 for Mac to be declared final.
