sending arrays has the same bandwidth as sending value by value, and if you
have to send a 176khz stereo stream to your gui over a network or whatever i
can still imagine problems.

i understand that from the design it makes sense to process dsp-gui
communication via the host, but i fear in real live a lot of plugins simply
don't do that. and i think to rework these communication is a big task for
most pluginvendors and may gives a bad feeling to GMPI, because of this.

that's why i suggest to make this an optional feature, allowing the host to
decide how to handle the gui.
