OK. That should be true indeed.
As for parameter dependencies when actually changing parameters, is this on
the table now? To be clear: if I change parameter A, and parameter B also
changes as a result of that, does that need to be specified in advance in
the parameter properties, or will it be handled using some kind of
notification scheme?

Really makes me think of OSC, so I'll repost this from a while back:
"In this context, maybe OSC (Open Sound Control) can be interesting: it
allows you to set up a hierarchic structure of grouped parameters for
sending over streams (also network).
http://cnmat.cnmat.berkeley.edu/OSC "
Note that this is an *existing* protocol and is actually being used (amongst
others for controlling Flash animations, for controlling synthesizers, for
making connections for parameter control between EyesWeb and pd (also on
different machines!), ...)
