Hi Thomas,

I can't answer your question about Jack ports because (I assume) the ports
are likely to be different on different machines so there probably isn't a
simple answer to that one.

On the audio side though, I believe that 'native' audio (i.e. audio residing
in "interchange/proj_name/audiofiles") is referenced by name alone.
Therefore it offers the ability to move or rename a project without needing
to copy all the media.  This is a step in the right direction - but the
technique used by most modern systems is to offer a "media pool" that
contains the media for all projects.  This makes it incredibly easy to copy
and rename projects - but less easy to move them.  The main drawback of the
"media pool" approach is that it usually requires all media names to be

In my AAF import code, I've arranged for all media to have unique names (in
anticipation that something akin to a media pool might emerge later).
However, there's some merit in the "interchange" arrangement because it
should (unless I'm missing something) make it quite simple for you to move
your project and your audio, as long as the media isn't embedded (although
you might still need to re-assign ports).

If a media pool approach emerges in the future, it might be necessary to
consider AES31 as the favoured import/export format.  AES31 can accommodate
features like overlapping audio and assymetric crossfades - neither of which
are supported by OMF or AAF.
