From an application programming point of view I don't want to have to profile my application for each target system. I'd very much like to run a few AV frames, BGP Hellos or whatever and then say "deadline schedule me that". It would be nice if the APIs were better thought out so that this could be simple, but they aren't. The current APIs really encourage reserving the worst-case behaviour of the algorithm on the worst-case target (not really appropriate for a soft real time such as video decode or protocol handling, where we can let the occasional extraordinary event pass through to the keeper), so we can be asking for two or three orders of magnitude too much resources.
