Hmm, do you have some specific use-case in mind?

This feature might be a bit confusing - what happens when you issue
"setpos", "fw" and similar command in iactive mode...?

Or were you thinking about limiting ecasound's access to only certain part
of an audio file...? So something like:

foo.ewf:
--cut--
source = foo.wav
limit-start = 60
limit-end = 120
--cut--

ecasound -i foo.ewf -o bar.wav

... would be equal to:

ecasound -i foo.wav -y:60 -o bar.wav -t:60

Btw; The ewf-field name 'source' is not very good. Maybe just
     rename it to 'file' or more generic 'object'?
