Thank you for this initiative, it sounds like an interesting solution to the problem I'm trying to solve. Will you post progress news here, or is there a better channel? The main upside of your approach is that it uses a standard protocol, but the main downside for now is that it does not exist yet. So I'm still curious, has the saned protocol been stable in the past? Are there hidden downsides to using saned as it exists now? Guillaume Girol
