Many thanks, gritzko It doesn't say very much, but it's something But, seeing as the actual protocol seems to be secret (and rather hard to reverse-engineer, I don't expect to pull that off before the RFC is released, unless it really takes half a year or something), is there any idea when it might be ready? Of course I'm not expecting any promisses, but it'd be nice to have some kind of idea as to when it might be ready..
