"Just" make the implementation imitate some old Spotify Connect hardware that isn't being updated anymore and it would be near impossible for Spotify to realistically tell the difference. Sure, people would still worry about using such software, but from an engineering standpoint, unless there's a signed Spotify Connect chip that for some reason can't be emulated, there isn't much Spotify can do to detect well-implemented reverse engineered API clients. Not something you throw together in a day obviously, but definitely not impossible.
