Bonjour syncing still working better than before, but dropped wifi connection does occur every now and again. Restarting OmniFocus on the Mac seems to fix this now though. Something about my setup has obviously changed. The only two significant differences I am aware of are the upgrade of iPhone to iOS 4.1 and enabling of web sharing on the mac.

EDIT: Had some time to play around with OmniFocus this morning so tried turning web sharing on and off, adding items to OmniFocus and syncing with iPhone. As far as I can tell, enabling/disabling web sharing is having no effect at all. I can only assume the upgrade to iOS 4.1 has fixed 'something' that makes bonjour syncing more reliable.

EDIT2: I spoke too soon. When I disable web sharing the first sync completes successfully, but repeat syncs fail with the message 'specified sync server could not be found'. Enabling web sharing on the mac and restarting OmniFocus on iPhone results in bonjour syncing working on successive occasions.
