Okay, what about if you have a song almost prepared, but it lacks, say,
something like a guitar solo? So, you have a perfect spot for it, but you
have difficulties in getting into the groove immediatly after you
pushed the start-button. You perhaps want to jam a bit with the song,
before going to the hot spot? Ok, you could edit the crap out
afterwards, but that adds one step you cannot (at least currently) perform
in commandline. (or what about sox?)

Yep, it might be.

No, I was just thinking about extra disk-activity in predefined timespan
in the cs. I mean, you use ewf's in input mode so that you write the .ewf,
then push start, and the .wav plays at the time specified in the the .ewf .
Why wouldn't you be able to do the same in output mode?

I vote 'object'.
