For this use case I don't trust implementations that I have source code for, due to their complexity. This is intended to share screens that lie behind a firewall. It wouldn't make sense to trust third-party code with closed source code and a similarly complex protocol (and undocumented). Neither would be logical to add this third party, the middle-man, as a point of failure and attack.
