I agree with just about every bit of that :) Thanks for the response! I think this makes the most sense, remote with some sort of local caching. Leads to a bit more implementation though and questions like:

1) What happens when they post something but don't have internet, would it store locally then sync up when it can? Or, just not allow posting without internet (curious how many people workout with an iPod Touch).

2) What happens when we get a new call from the remote server, kill the local table entirely or have some field on each record like "synced" that lets you check for records that need to be updated still?

Anyways, just a few things like that but thanks a ton, you gave me some more things to think about :)
