Would acoustic echo cancelation work if I setup different audio unit graphs ( one graph with only input enabled, and 'n' graphs with only output enabled )?
Each graph would rely solely in the voice processing io audio unit.
Thanks a lot, Daniel

You are only allowed one remoteIO per app on iOS. So I believe the n outputs scenario isn't possible. You can, however, use one graph, split the input to multiple nodes, then mix them back in with a mixer connected to the output.
