I’m testing the capabilities of posting entries to my wordpress in offline mode via the iPod touch apps. In the app,you can create a new entry on offline mode under the local drafts category. I would assume that you would be able to create entries and then post it online when you are connected to the Internet. This would be a fine feature as I can update my blog under both online and offline modes using the wordpress platform. Updating it would simply be connecting to the Internet and publishing the drafted entries.
