Sorry, you didn't mention that you are also syncing with an iPhone. Unfortunately, you only get to choose one sync method. If you were very careful, you could possibly get away with switching back and forth, but you always have to make sure everything is synced up before you switch methods or you'll risk losing some changes. So, you could use SugarSync to sync the work machine and the home machine, and the home machine you would flip back and forth between sync to disk (to collect/send changes to/from the work machine) and sync via Bonjour (to sync with the iPhone). You probably would not want to make changes on the iPhone if there are changes from the work machine that haven't yet been synced back to the home machine, which could greatly diminish the usefulness of this setup.

Disclaimer: I haven't tried switching back and forth between disk sync and Bonjour sync, only between disk sync and webDAV sync. I make no promise that this will work for you, or that it is even a good idea to try. Might be easier to just use the iPhone at work!
