I'd much rather see a WAP/HTML method of input. (potentially more expensive for phone users, but at the same time, far more reaching than writing either an app for each device, or syncing methods that are probably better suited for another product)

I would absolutely love to see a simple web interface where I can focus on a specific context (Errands, for example) - easily checking lists off my shopping list, via my iPhone.

Or, using Safari's ability to make dashboard widgets out of any web page, have a dashboard widget (perhaps on a second computer, maybe at work) for another context.

After watching Ethan's overview video, this seems like a very logical next step for OmniFocus (hell, assuming the API is there, I would most likely hack together such a web service for my personal use if it's not included, and allowable)
