As a note here, while most of this discussion is happening over at unicornation at the moment, I wanted to tell you all I have been experimenting with FX plugins HEAVILY at the moment.
For time dependent value information (filters, compression) the results out of DP and Logic are different, dynamic wise on compressors even, and I am trying to figure out why. Things like gain in a plugin work as expected (null to zero).
I am in the process of looking for or while have to write a plugin to examine what the host is asking of the plugin. This way, I can see if this is a time scale issue, time slice issue, or what.
Hold on to your pants!

Interesting stuff.
