I > prefer a conf call as the medium is better for resolving disputes ] <ml>The problem I have with a conference call is that many people on the TC find it difficult to attend them and if we are to vote on this then we really should try to reach the largest audience possible. An educated vote is obviously what we would want to achieve. So, if we did a teleconference then we would have to minute it in detail and send that round and then get feedback from people on the mailing list and ... And purely on a personal basis, at the moment I'm spending more than enough time on teleconferences. Email I can do from home or anywhere. </ml> <ml>I'd just like to stress a couple of point again: (i) we have never said that this functionality isn't required, only that it may already be possible in another way and that we should take it one step at a time: let's learn to walk as a specification committee before we try to run. IMO the 1.0 version of the specification will be like any other 1.0 I've ever seen: people will look at it and find fault with it and the 1.1 version will be the one that most people will use. So, let's do this in a 1.1 timeframe where we have more time to carefully consider our options. (ii) the business case you briefly outlined does look at first glance like it could be done using interposition (subcoordination). From a protocol point of view I'd like to see this explored to see why (and if) it doesn't match your requirements. </ml> > > > > > Mark. > > > > > > > > 9pm PST works on the 25th / 29th April. > > > > > > > > > > > > Mark Little wrote: > > > > > > > Geoff, I'd be happy if you could also answer all other queries in the > > marked > > > > up Word document and previous emails on this subject.
