Sorry I haven't gotten back to you earlier, I was in Europe for a couple
weeks, including giving a talk at GUADEC (where most of the GStreamer
developers finally met in person for the first time).

I'm compiling Overflow right now, and like what I see.  It sounds like the
perfect tool to work on one of my other pet projects, which is codec
development (new code, not new implementations), among other things.

At GUADEC I was approached by a guy working on another somewhat related
project (graph of decision processing, that he compiles to C, used for
things like deciding whether to grant a loan or not) that has a *MEGA*
canvas-based graph editting system called Seashore.  He says it'll be out
(LGPL'd) in a month or so, if there is enough interest in collab between
various graph-based projects like GStreamer, Overflow, aRts, etc., I can
probably convince him to release a copy to us earlier, for feedback and
such.

Seashore is based on the AA canvas, and as such has all sorts of neat
interaction stuff such as alpha-fading links and such.  More importantly,
it has massive graph-structuring code, with spline links and all that.
