I don't mind aggregated/processed/sanitized data going to the cloud. I don't want a raw audio feed going to the cloud.

If my local processing appliance tries to upload anything beyond a well-defined set of messages and bitrates, I'll get suspicious.

An innovative concept - the server software is installed on raspberry pi I own.

What'll be easier to hack - a raspberry pi that Holly Housemaker maintains or a cloud connected one that Nick Neckbeard maintains for her? (serious question, I think there's a debate here)
