Personally, irrespective of protocol, what i would like to be able to do is to live stream the decoded data down to a host pc for further processing. That way, I get the triggering, channel and sensitivity flexibility of the scope coupled with the data chewing capabilities of the pc. It's possible that this can already be done (i haven't looked in any detail, i have other tools that are usually good enough) but it's certainly not a use case I'm comfortable using a scope for.
